Finding The Energy Given Off From Various Fuels EssayResearch Question Which of these provokes (ethanol, methyl alcohol and butanol) releases the most kinetic energy per ringitt?Hypothesis ethyl alcohol will release the most kinetic energy per ringitt because it has an average tot up of CH compounds (Materials Spirit burner with ethanol 3 aluminum ignores Spirit burner with methanol Logger Pro Spirit burner with butanol Insulated container Matches Ring Stand Graduated Cylinder 150mL of waterProcedure1. Pour 50mL of water into the first aluminum can2. Place the can 7cm above the ground on the ring stand3. Place the Logger Pro inside of the can4. Light the spirit burner of the fuel under the can.5. Close the container around the ring stand and the spirit burner6. Stir the Water inside of the can constantly.7. Record the temperature of the water for 3 minutes.8. Repeat the move for each type of fuel.9. Find the number of kilojoules released by each of the fuels10. Find the amoun t of kilojoules of each fuel when there is 1 liter of that fuel.11. Divide the amount of kilojoules/litre by the cost/litre of each fuel.12. Choose the fuel with the most kilojoules released per litre.Data Collection and ProcessingEthanolMeasuring the Mass of EthanolTime Alcohol Container Was BurntMass of Alcohol Container (g) to begin with importunate160.2After Burning158.9Measuring Temp. of EthanolTimeTemp of Fuel (C)Before Bunrning24.6After Burning93.8MethanolMeasuring the Mass of MethanolTime Alcohol Container Was BurntMass of Alcohol Container (g)Before Burning191.4After Burning190.1Measuring Temp. of MethanolTimeTemp of Fuel (C)Before Bunrning25After Burning60.8 butyl alcoholMass of Alcohol Container (g)MethanolEthanolbutanolBefore fervent191.4160.2190.8After burning190.1158.9190.5Temp of fuel CMethanolEthanolButanolBefore burning2524.623.8After burning60.893.844.8Finding the Energy Released by The Fuels (Q = m x C x ?T)Step 1 Finding the ?T (change in temperature) ?T= endin g temperature starting temperatureStep 2 Finding the Heat Capacity of Water (C ) Heat capacity of water = 4.18 J/gStep 3 Find the people of water Each can had 50mL of water 1mL = 1 g Each can had 50 g of waterEnergy released by EthanolQ= 50 x 4.18 x 69.2Q= 14.5 kilojoulesEnergy Released by MethanolQ= 50 x 4.18 J/g x 35.8Q= 7.5 kilojoulesEnergy Released by ButanolQ= 50 x 4.18 J/g x 21Q= 4.4 kilojoulesEnergy Released by ethanol per ringittKilojoules/litre = 11153.8Energy Released by Methanol per ringittKilojoules/litre = 5769.2Energy Released by Butanol per ringittKilojoules/litre = 14666.7
