Finding The nil Given Off From Various Fuels EssayResearch question Which of these fuels (ethanol, methanol and butanol) releases the most energising energy per hem initt?Hypothesis Ethanol will release the most kinetic energy per ringitt because it has an average amount of CH compounds (Materials Spirit burner with ethanol 3 aluminum cans Spirit burner with methanol blighter Pro Spirit burner with butanol Insulated container Matches Ring Stand Graduated Cylinder 150mL of waterProcedure1. teem 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 on a lower floor the can.5. Close the container around the ring stand and the spirit burner6. Stir the Water inside of the can constantly.7. study the temperature of the water for 3 minutes.8. Repeat the steps for for each one type of fuel.9. Find the number of kilojoules released by each of the fuels10. Find th e amount of kilojoules of each fuel when there is 1 liter of that fuel.11. Divide the amount of kilojoules/ cubic decimetre by the cost/litre of each fuel.12. Choose the fuel with the most kilojoules released per litre.Data Collection and touchEthanolMeasuring the Mass of EthanolTime inebriant Container Was BurntMass of Alcohol Container (g) ahead Burning160.2 afterward Burning158.9Measuring Temp. of EthanolTimeTemp of Fuel (C) earlier Bunrning24.6After Burning93.8MethanolMeasuring the Mass of MethanolTime Alcohol Container Was BurntMass of Alcohol Container (g) originally Burning191.4After Burning190.1Measuring Temp. of MethanolTimeTemp of Fuel (C) in the first place Bunrning25After Burning60.8ButanolMass of Alcohol Container (g)MethanolEthanolButanolBefore burning191.4160.2190.8After 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) stride 1 Finding the ?T (change i n temperature) ?T= ending temperature starting temperatureStep 2 Finding the Heat Capacity of Water (C ) Heat capacity of water = 4.18 J/gStep 3 Find the mass 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
