How does the Relative Molecular Mass change in heat combustion of an alcohol? :: GCSE Chemistry Coursework Investigation

How does the Relative Molecular Mass change in heat combustion of an alcohol? Planning Introduction ============ As alcohol burns in air it gives out energy as heat and light. I am going to investigate how the energy output of an alcohol in combustion changes, with increased relative molecular mass, or RMM. RMM is the sum of the atomic masses of every atom in the molecule. Using the alcohols: Methanol, Ethanol, Propan-1-ol, Butan-1-ol and Pentan-1-ol, I will plan, and complete an experiment that tests the prediction below. ====================================================================== Prediction And Theory ===================== In the combustion of alcohols in air, the alcohol reacts with oxygen molecules, to create carbon dioxide and water. Many bonds are broken in the process using up energy. At the same time, the atoms reforming into the new molecules of carbon dioxide and water give out energy. In the combustion of alcohols, the energy created, when forming bonds will always be more that what is lost, when breaking bonds, this gives us excess energy. This energy is given out primarily as heat, but also as light and sound. As energy is given out it is called an exothermic reaction. If the opposite were true, it would be an endothermic reaction. It is never possible to calculate exact energy change by experimentation due to inaccuracies and energy waste, so we use bond energy calculations give the exact theoretical energy change. Bond energy calculations show that the higher the RMM the more energy will be produced for the same weight of fuel (RMM is the sum of the atomic masses of every atom in the molecule). This is because as the RMM increases there are more atoms and therefore, more bonds to be broken and then made. As, when burning alcohols, this process gives out energy, the more bonds go through this process, ie as the RMM increases the more energy should be released. The calculations also suggest that for every carbon atom you add to the chain of an alcohol the energy out should increase by 618 Kj/mol. I predict then, that as the RMM goes up then the energy change will get increasingly more negative i.e. more energy is given off. The RMM will be proportional to the final energy created as both should increase by the same number each time, (RMM by 14 as one C and 2 H atoms are added, and the energy out by 618KJ/mol). This will therefore result in a straight-line on the graph. The bond energy calculations show how much energy should be released, accounting for experimental inaccuracies however, I expect the experimental output to be considerably less. Proposed Method I am going to test how the energy output per mole in the combustion of

Blender Blade Component Analysis Engineering Essay

The blade constituent in the liquidizer is map to suppression and blending the ingredient with a really fast revolving velocity. First we need to understand the construction of the blade to enable the blade execute the procedure like sliting and softening. We know blade necessitate to be fixed under high rotational velocity operation, therefore the blade must hold the high modulus of rigidness to forestall any deformation during the operation. It is because the shearing force Acts of the Apostless on the blade is really high due to its velocity. Since it is rotate in high velocity when the nutrient are being dump into the nutrient container, it will do a impact acts on the blade that will do the blade to interrupt or check if the blade do non tough plenty. Besides that, the shaft will maintain in contact with the nutrient and ever expose to the nutrient chemical, therefore it must be entire chemical inert. The corroding procedure must non be occurred to forestall wellness risky incident. The high wear opposition is besides of import to the blade, as it will ever run for the interrupted procedure. The cyclic burden will do fatigue therefore we need difficult blade. Normally wear opposition can be increase by making a coating on the blade. Crisp borders with good strength is besides really of import to enable the blade execute the mincing or crunching procedure expeditiously. The blade is various plenty to cut about all the nutrient stuff that can be intermix if needed, strength once more is needed. Here is the drumhead degree Fahrenheit the liquidizer blade belongingss that we use as guideline in blade stuff choice. Hardness High strength Stainless steel High rigidness High wear opposition2.2 MATERIAL SELECTION2.2.1 BLENDER BLADE MATERIAL SELECTIONIn the choice stuff we must see many facets to guarantee the merchandise that we have made successful in overall facet. There some standards that must be see such as: Physical & A ; Mechanical Considerations Thermal Considerations Chemical Considerations Bearing and Wear Considerations Cost Type of utilizations and etc To get down the material choice of the constituent, we have to utilize the assorted comparing charts to compare diverse of stuff that available. In this clip about, we use the specific stiffness to specific strength, strength to cost, strength to toughness, and immature modulus to denseness. These are primary chart that we use to guarantee our choice. In the specific stiffness to specific strength chart, we can acquire the consequence of the stuff that has medium specific strength and high specific stiffness. This is an of import standard of stiffness in our merchandise. In the strength to be chart, we need to compromise the cost and the strength that we can keep competitory monetary value with the strength for safety. In the immature modulus to density chart, we need to hold the mid scope of denseness to forestall corpulence of merchandise with the high immature modulus. High immature modulus means that the emphasis that the, stuff can defy before it ‘s deform. In between strength and stamina, we need to hold both for the blades do non neglect prematurely particularly face the impact gesture of the nutrient encountered by blades.Figure 3: Strength AND TOUGHNESS COMPARISON CHARTFigure 4: Specific STIFFNESS AND SPECIFIC STRENGTH COMPARISON CHARTFigure 5: Young MODULUS AND DENSITY COMPARISONFigure 6: STRENGHT AND COST COMPARISON CHARTFrom the comparing we have made above, the suited stuff that we can take is chiefly metal stuff either alloyed or non. But we need to see corroding procedure that will that topographic point for ferric metal. Then we can take either alloyed metal or ferric alloyed metal like chromium steel steel. In the consequence we get, we besides found the stuff to applicable to our blade constituent production like ceramics. The ground we do non take it as comparing because of its crispness. We can non hold the toffee will do it crack when it is over it ‘s bound so will do the safety job. Based on the characteristic we found in the constituent, We have decide to compare two stuff in doing blade of liquidizer: Alloy steel Stainless steelAlloy Steel Properties[ 5 ] Alloy steel is the steel that contain some alloying elements like Mo, manganese, nickel, Cr, V, Si and B. Compare with C steel, the belongingss of Alloy steels have greater strength, hardness, hot hardness, wear opposition, hardenability, and Toughness. However, to obtain the require belongingss, they are needed to be heat treated.Stainless Steel Properties[ 6 ] Stainless steel differs from C steel by content of Cr in steel. The chief different belongings of the chromium steel steel is its corrosion opposition. Carbon steel rusts when exposed to air and wet. This Fe oxide movie is active and accelerates corrosion by organizing more Fe oxide. Stainless steels have sufficient sum of Cr nowadays so that a inactive movie of Cr oxide to forestall farther corrosionBlade stuff Comparison ChartSTAINLESS STEELParameterALLOY STEEL620 MPa.Ultimate tensile strength570 MPa. 240-290 MPa.Output strength440-500 MPa. 20-24 %Elongation15-18 % aˆ?

Hi strength comparison to chromium steel steel but less ultimate tensile strength.Selected Blade Material – chromium steel steelIn doing blade, we have decided to utilize unstained steel because of some ground. The most of import is because we need the stuff that have excellent in corrosion and oxidization opposition. This is because we deal in doing nutrient processor. So that the quality of nutrient is chief thought to guarantee the user is safe to utilize is. Other than that, chromium steel steel has high wear immune. This belongings is good to hold in doing the blade because it ever crisp in cutting the nutrient. The impact stamina is besides the portion that we tend to take 304 steel since we have rotate in high velocity to cut or slit the nutrient. Stainless steel besides has a batch of categorization that we can take for the production of the blade. Therefore we have to take a specific category to guarantee the cost appraisal. After we did the research, we decide to take unstained steel category 304 to be our stuff for the p roduction.Stainless Steel – Grade 304Fe ; & lt ; 0.08 % C ; 17.5-20 % Cr ; 8-11 % Ni ; & lt ; 2 % Mn ; & lt ; 1 % Si ; & lt ; 0.045 % P ; & lt ; 0.03 % S [ 7 ] These are some of its features: – Forming and welding belongingss – Corrosion/ oxidization opposition – Deep drawing quality – Excellent stamina – Low temperature belongingss reacting good to indurating by cold working – Ease of cleansing, easiness of fiction, beauty of visual aspect.

But every procedure must has it ‘s restrictions and ain advantages. The procedure selected is shown at table below:Figure 7: Blade Manufacturing Alternative ProcessesSince we have chosen the stuff, so we have look at the procedure to bring forth the merchandise. There are diverse of procedure of available outside, we need to take suitably to suite the stuff belongingss and the functionality of the constituent. There are several guidelines that we need to obey. The choice of a suited procedure is based on the undermentioned factors: Types of stuffs and its belongingss Expected quality and belongingss of the constituents Size, form, thickness and complexness in bring forthing the constituents Tolerances and surface coating Incoming procedures involves Design and tooling cost Volume of production Economy Now the chart above has shown 3 primary procedures that we will discourse further to take the best production procedure. Now we discuss the casting procedure. The procedure is a popular fabrication procedure that can hold many advantages. The grounds why we choose the investing casting procedure among assorted procedure of casting are because any stuff can project through this method. The investing casting procedure is economical even for rather low measure usually minimal measure is 1000. Furthermore, the complex form can be produced which meet the blade design. Heat intervention of the casting merchandise is non needed. Excellent surface coating and truth besides can be produced through this method. Again it suites the constituent demand that dimensional and surface coating. But the procedure has the disadvantages. We have the expensive dice tool and stuff cost, long lead clip to hold the concluding merchandise, labour cost is high. After we have seen the procedure we have the clea rer image of the procedure. The following procedure we will discourse the forging procedure. The blocker type of the forging will be used in this procedure. This is because this type has the low dice cost compared to other forging procedure. The production rate is high that will run into the company minimal production demand. Forging will hold the dice to use the compressive force on it in order produce the form we want. In the blocker forging, demand to make the machining to acquire the net form we want. The portion will non be a suited pick if the parts are thick webs and big filets. The chief cost is come from the dice cost which influenced by form and size of the constituent. The measure is besides the major concern in cost footing fabrication. Then we will make the stamping treatment. Stomping besides the sorts of sheet metal organizing utilizing the stamping dice and use the force on the sheet stuff. [ 18 ] The cost effectivity of the metal stomping procedure stems from its ability to bring forth material-intensive parts at production rates much higher than are possible utilizing other traditional methods. With stuff for stomping about bing use in another procedure, the premier country for nest eggs is in cutting production clip. From the above treatments, we can see that stomping will convey us the most economical procedure. Although we need to bear with the high start-up cost, but through the long term, the turnover is still good. The investing casting is excessively arduous and long lead clip which does non suite our selling policy ; the forging is more suited for big constituent.3.2 PROCESS SELECTED AND TOTAL PRODUCT STAGES3.2.1 BLENDER BLADE MANUFACTURING PROCESS3.2.1.1PROCESS SELECTED FOR BLENDER BLADEAfter weighing the pros and cons of procedure, we have chosen the stomping which derived procedures from progressive dice drawing. [ 22 ] By utilizing stomping procedure, there are some advantages compare with other procedure like hammering and die casting. First of wholly, the stomping dies can be well less than the tooling used in other procedures. Other than that, the Quality, truth, map, wear life and visual aspect can all be dramatically improved. By utilizing stomping procedure, the portion of stuff with tougher and harder belongingss can besides be made. Secondary operations like heat intervention and machining are needed to complete a portion. The figure of secondary operation is reduced and it can salvage the cost. To bring forth liquidizer blade by stomping procedure, there are some secondary procedure to be taken in. after the constituent is stamped out from the stamping machine, we need to bore a little hole on the constituent for the assembly intent. After that, flexing procedure will take in to obtain the functional form of liquidizer. Then, the constituent is so to be heat treated to better its mechanical belongingss like strength and stamina. Finally, a finishing procedure will take in to sharpen the blade border by machining procedure and better the wear opposition by add-on procedure like coating of blade with Ti.3.2.1.2 BLENDER BLADE STEPS FLOW CHARTThe phases for blade fabrication system are shown in the stairss flow chart below:Figure 8: Phase OF BLADE MANUFACTURING BY STAMPING3.2.1.3 BLENDER BLADE PROCESS STAGE AND MACHINE USEDStompingThe procedure is start by stomping of a big sheet of metal. We will utilize blanking procedure which is a cutting procedure by utilizing clout and di ce to bring forth the blade profile. For blanking procedure, the merchandise is the portion which is sheared out by clout. To transport out the blanking procedure, the stamping dice and stomping machine is needed. The blade merchandise by blanking procedure is shown at the figure below: Component ( merchandise ) Strip ( work stuff ) Scrap ( discard )Figure 9: blanking of bladeFeatures Of Stamped Parts[ 22 ] after stomping procedure, there are BURR-SIDE or CUT RADIUS feature on the stamped parts. There is a unsmooth border or breaking away burr around the side of the perforated holes. At The opposite side, there is a cut radius or â€Å" rollover † consequence where the blanking or piercing punch enters the metal surface. Both of these defects can be corrected if they affect the map ablility of the constituent. Deburring procedures can be used to take the burrs. Deburring procedure is done by utilizing deburring tool, toppling, or sanding. Drilling will do the holes straight through the full portion thickness. A shaving station in a progressive dice can cut down the demand for secondary handling operations. Besides, utilizing thicker stock than the concluding size called for and dual phonograph record grinding, or individual side grinding, as required will take burrs and rollover. After stomping procedure, the phenomena of CONCENTRICITY can be found on the merchandise itself. The contour of the interior and outside shows different belongingss and even thicknesses. the discrepancy can be cut down by excess allowance to the merchandises made. Besides the concentricity, the flatness/blanking deformations besides common phenomena that occur in the stamped merchandise after stomping procedure. There is the bowing rise in the merchandise due to periphery emphasis. The size of the obeisance varied with the stuff and type of dice used. The solution of the defects can be through the use of compound dice.Machine used for stomping procedure – Stamping MachineIn the stamping machine the major operation is where a metal sheet is being punched utilizing a imperativeness tool in order to give out into coveted form. Different stomping procedure necessitate different type of dice. Example of blanking dice is shown in figure 9Figure 10: Stamping MachineFigure 11: Stamping DieDrillingOnce the constituent is stamped out, the boring procedure will take in to bore a hole on the blade for the assembly intent. A boring machine is needed to bore the hole. The constituent after boring procedure is shown in the figure below: Drilling machine Component ( Merchandise )Figure: Drilling Of BladeMachine Used – Drilling Machine[ 23 ] A boring machine, called a drill imperativeness, is used to cut holes into or through metal, wood, or other stuffs. Boring machines use a boring tool that has cutting borders at its point. This cutting tool is held in the drill imperativeness by a chow or and is rotated and fed into the work at variable velocities. Boring machines may be used to execute other operations like countersinking, drilling, counterboring, topographic point facing, reaming, and tappingFigure 13: boring machineBendingTo obtain the better map ability of the liquidizer blade, the form of the blade should be flexing with certain angle as shown in the figure 9. This is a fictile deforming procedure to alter the form of metal blade. Note has to taken that the flexing portion of the constituent is under high emphasis after the bending procedure. To get the better of it, heat intervention will taking topographic point to hardening and reconstruct the emphasis. The constituent after flexing procedure is shown at below:Figure 14: Bending Of BladeMachine used: Bending Machine[ 24 ] Bending is a common fabrication method to treat sheet metal. It is normally done on a Press brake, but besides swing-bending-machines are used. With this machine a bending stuff is being bent by following the preset angle as a mention. The bending operation creates a consecutive line crook while form operation may make a curving crook.Fi gure 15: CNC Bending MachineHeat intervention[ 25 ] To reconstruct the residuary emphasis that trap in the stamped merchandise, heat intervention is normally carried out. Heat intervention can heat the metal to recrystallization temperature that will realine the grain in the metal. The heat intervention of the metal, the cleft can be reduced and it can be hardened as the finer grain can be obtained. The undermentioned describe the procedure heat intervention of the blade. The blade ballad on the ceramic tray so heat up to the specified temperature to indurate the portion. The oven normally is preheated to faster the procedure. The warming procedure last for 2 hours. After procedure the ceramic tray take out from the oven. The submergence of the merchandise into oil or H2O to execute slaking. This trap the intricate crystal in the metal construction. This procedure besides consequences in the metal going really brittle. After slaking, the blades are reheated to about 260A °C. Then the blades are allowed to chill easy in a procedure called annealing. This toughens the metal while retaining some of the crispness needed for all right sharpening. Further warming and chilling rhythms may be used to indurate other specialised metals.Machine Used: Heat Treating Oven[ 26 ] Heat handling oven is usage to heat the stuff up to 760A °C – 1370A °C It has the map to command the temperature and force per unit area of warming. The box furnace can manage exothermal, endothermal, and enriched ambiances including air, N, and Ar.Figure 16: heat handling ovenMachiningFinally, the blade will undergoes machining procedure as the coating procedure. [ 25 ] After the heat-treated blades are cool, they are polished and sharpened. Polishing is performed by machine in our instance. A level belt smoother is used to bring forth a smooth coating to the sides of the blade. This besides polishes out any Markss from the punch imperativeness operation and removes the surface residue from the heat-treat operation. Next the blade is placed into a grinding fixture that passes it through a series of crunching wheels. Each revolving wheel removes the right sum of metal to organize the border alleviation, point, rough border angle, and other characteristics of the working part of the blade. When the blade is finished with these stairss, it will be rather crisp and may look ready to utilize. However, the concluding sharpening stairs s are required to bring forth a durable border. Honing is the last procedure to take in. the crisp border of blade is produced by a all right grinding operation and called honing. The angle of the hone may be between 17 and 30 grades to the axis of the blade, depending upon the blade application. A smaller angle will bring forth a sharper border, but the border will have on and go dull more rapidly. A all right grinding hone, or â€Å" rock, † is oiled and gently rubbed on the knife border. This action produces the finest sharpened border.Machine Used: Belt Sander[ 27 ] A belt smoother is a machine used to sand down wood and other stuffs for finishing intents. It consists of an electrical motor that turns a brace of membranophones on which a seamless cringle of emery paper is mounted.Figure 17: Belt SanderConsequence on plagiarism checker on hypertext transfer protocol: //www.articlechecker.com/checker.phpMatched PhrasesGoogleA ResultsA Found:MATERIAL SELECTION 2 ( Set Alert ) Carbon steel rusts when exposed to air and wet ( Set Alert ) This Fe oxide movie is active and accelerates corrosion by organizing more Fe oxide ( Set Alert ) Ultimate tensile strength 570 MPa ( Set Alert ) aˆ?

An Omnipotent Government: Utopia or Dystopia Essay

â€Å"Utopia: an idealized place of perfection or a visionary scheme for a perfect society† (Agnes). However, what if the ideals of utopia result in the seeds of dystopia? What if a government that is able to rule a perfect society, oversteps its bounds and causes destruction of freedom? In the dystopian novels 1984, A Brave New World, and The Giver, the government controls every thought, every fear, every story, and every emotion. These novels warn of the threat of a government that becomes too involved in its citizens’ lives. When citizens allow themselves to be uncaring and uninformed about their government, the ultimate price is freedom and liberty. These novels show that freedom is much to high a cost; momentary contentment should never come at the expense of liberty. Adolf Hitler once said, â€Å"If you tell a big enough lie and tell it frequently enough, it will be believed† (Huxley). Propaganda is a very powerful tool that can be used for good or evil. In 1984 the Party’s slogan, â€Å"WAR IS PEACE. FREEDOM IS SLAVERY. IGNORANCE IS STRENGTH,† convinces its citizens that they want what the government has given them: war, slavery, and ignorance (Orwell). They do not want freedom because it is slavery. They are made to believe that peace and serenity come only during war. They are uninformed about their world, and this gives them strength. This type of government propaganda controls what citizens think by controlling what is heard on the radio, the television, the newspaper, and all other forms of media. In A Brave New World, propaganda is not only forced on citizens through media, but also during sleep. At the time Huxley wrote his novel, a new technique of â€Å"sleep learning† had become popular. The technique hypnopaedia was an interesting concept but actually caused negative behavior. Huxley used this in his novel as a form of government brainwashing. In A Brave New World, those in power used â€Å"sleep lea rning† to instill their beliefs in the citizenry of London (Clareson). This â€Å"sleep learning† is a type of non-rational propaganda. Huxley compares the two kinds of propaganda, rational and non-rational. Rational propaganda appeals to a person’s own best interest. Rational propaganda can only be used in a society where people have reason and morals. They could use the propaganda to rationalize what is in their best interest. Nevertheless in a society without reason or morals, what kind of propaganda is effective? Non-rational propaganda appeals not to any person’s best interest, but to their emotions. â€Å"The power to respond to reason and truth exist in all of us. On the other hand, unfortunately, does the tendency to respond to unreason and falsehood—particularly in cases where the falsehood evokes some enjoyable emotion† (Huxley 265). Huxley applies Hitler’s rule that the behavior of the masses is not determined by knowledge, but by feelings and innate drives. The propaganda in A Brave New World appeals to passion instead of reason (Clareson). Punishment is a powerful method of controlling any person. The fear of something that causes pain or unhappiness is usually an effective way to keep a person from rebelling. In The Giver, the fear of â€Å"release† or death kept all the citizens from breaking any rules. Even a simple mistake could cost a life. When a pilot in training accidentally flew over the city, the elders comforted the citizens, â€Å"Needless to say, he will be released† (Lowery 21). The citizens in The Giver did not understand that â€Å"release† meant death, but they could comprehend that it was not a desirous thing. In Lowery’s novel, no one broke rules. When Jonas’ father looked at the name of a baby before the naming ceremony, Jonas was shocked. He could not believe his father had broken a rule. In 1984, many people were hanged for a crime. â€Å"Thought Crime† was punishable by death. The Thought Police could not watch everyone’s thoughts simultaneously, but if they came across a belief that did not align with the party, death was the result. However public execution is not the only form of death in 1984. â€Å"Disappearances† were a common occurrence throughout the novel. Often those guilty of â€Å"thought crimes† just disappeared. All records of their existence were erased, and the Party attempted to remove all memories of them through â€Å"double think† (Orwell). Huxley takes a completely different approach in his novel. Pleasure is the key to controlling the citizenry in A Brave New World. A review of the book states, â€Å"Pleasure is the most powerful motivator of man† (Clareson). Research has proven that rewarding good behavior is more effective than punishing wrong behavior. Where the citizens in 1984 are controlled by fear of punishment, the citizens in A Brave New World are controlled by reinforcing desirous behavior. The main tools used by the government to regulate society are sex and Soma, a drug used by all citizens in the novel. The people’s awareness is suppressed to th e point that the World Controller refers to them as â€Å"nice tame animals.† They sacrificed their entire future for the pleasure of the moment. If a citizen disagreed with the government in A Brave New World, they would be given soma and through â€Å"sleep learning† be retaught the importance of government and their place in society (Huxley). The government fundamentally brainwashes its citizens to keep them ignorant of anything other than what they need know. Knowledge is a valuable thing. â€Å" If a nation expects to be ignorant and free, it expects what never was and will never be†¦the people cannot be safe without information. Where the press is free, and everyone is able to read; all is safe† (Huxley). One important factor in controlling a large group of people is limiting his or her knowledge and resources. In 1984, the government uses a new form of speaking called â€Å"news speak.† Newspeak is a simplified version of the truth. The problem with this is when things are simplified we do not get the full version of the truth; instead we get a biased form of it. In 1984, the government controls information allowing only what reflects well on them to be released. â€Å"Don’t you see the whole aim of newspeak is to narrow the range of thought† (Orwell). Lowery also shows a limitation of knowledge in her novel. In The Giver, the elders censor their peoples’ language, emotions, and behaviors. Only the Giver and Receiver are allowed access to books and memories. The citizens in this novel are childlike in their understanding of things (Hanson). They literally have a limited vision and no way to think for themselves, or to make decisions without the Giver’s help. Taking away knowledge is a powerful thing and dangerous thing. â€Å"Who controls the past, controls the future: who controls the present controls the past† (Orwell 32). History and memories are essential to a society. When citizens forget the past; it numbs the entire citizenry. In 1984, the government constantly changes the past so it portrays them in a better light. â€Å"The party is at war with Eurasia therefore it always has been at war with Euras ia† (â€Å"Eternal Vigilance†). â€Å"Double think† is a form of thinking created by the government in Orwell’s novel. To â€Å"double think† is to have two contrary beliefs and believe both of them, while only expressing one. Orwell’s main character Winston knows when something is a lie, but has no evidence to controvert it. He says, â€Å" The past†¦had not merely been altered, it had been destroyed† (Orwell 33). In The Giver, only the Giver himself and Jonas the Receiver are allowed access to the history of their city. Upon discovering the outside world and time Jonas says, â€Å"I’m sorry sir. I don’t know what you mean when you say ‘the whole world’ or ‘generations before him.’ I thought there was only us. I thought there was only now.† Before becoming the Receiver, Jonas like all the others in his community only understood the here and now. To them everything outside of their own city simply was â€Å"elsewhere† (Low ery 56). When Jonas does discover his people’s past, he longs for a different future; knowing that there was more to life then what was offered by his elders. Emotion is an essential part of a human being. In these dystopian novels, emotion is either used as a tool for the government or completely eliminated from society. In 1984, negative emotions are used to create a common enemy among the people. Every day, all citizens were required to participate in the â€Å"two minutes hate.† During this time, they focused on an enemy of â€Å"The Party† and exhibited very animalistic behavior (Orwell 5). They also trained children from a very young age making Party minions. Winston describes his neighbor Parsons, â€Å"a man of paralyzing stupidity, a mass of imbecile enthusiasm- one of those completely unquestioning devoted drudges on whom†¦the stability of ‘The Party’ depended† (Orwell 22). Lowery instead of using emotions, tried to completely suppress them. In The Giver, there is no such thing as color, love, or joy. Jonas’ world is dependent of content people who ask few questions and see no need fo r change. Their lives are planned for them; spouses are picked out and children are applied for. All these monumental decisions are made by the council of elders. Jonas is accustomed to a life of â€Å"sameness.† Upon turning twelve and becoming the Receiver, Jonas’ lackluster world transforms into a vibrant new place. The memories given to him allow Jonas to experience love and warmth. â€Å"I like the feeling of love†¦but I can see that it was a dangerous way to live† (Lowery 126). In The Giver, â€Å"stirrings† are treated with a subduing drug. This represses any curiosity and imagination the young people have. Adults are also required to take medicine that eliminates their sexual desires (Henson). There is nothing beyond what is required and no desire for something more. In each of these cautionary novels, there are uneducated people who have no desire to become informed. Government has become so controlling that even history has been changed. Propaganda and emotions are only means to advance the government. Liberty is the price paid for stability, safety, and community. Their world did not become the desired utopia instead it became a dystopia. Webster’s dictionary defines dystopia as â€Å"a place where people lead dehumanized and often fearful lives† (Agnes). Liberty and freedom must be earned and guarded. Enlightened and empowered citizens must keep them alive. The dystopian life shown in these novels is only a threat if citizens allow their freedoms to be taken away. When citizens allow themselves to be uncaring and uninformed about their government, the ultimate price is freedom and liberty. These novels show that freedom is much to high a cost; momentary contentment should never come at the expense of liberty.
