Energy output of Bioethanol and Industrial Ethanol Essay Example for Free

vital force output of Bioethanol and Industrial Ethanol Essay studyThe aim of this investigation is to determine which of the two derivatives of ethanol releases more energy, Bioethanol or Industrial Ethanol.HypothesisThe main(prenominal)(prenominal) compound in both intoxicantic beverages has the same chemical formulae C2H5OH, and the other compounds are unknown therefore the Energy output fuelnot be calculated exactly by using standard bond enthalpies. However, as the main compound is known and the same for both ethanols the energy output should be very similar. thusly the oddment in energy output only depends on the compounds which are blended to the alcohols. Apparatus Thermometer Metal can x2 Draught shield x4 Gloves Safety spectacles Heat-resistant mat Insulation card 100cm3 measuring cylinder x2 feel burner Clamp stand Balance MatchesSubstances E100 Bioethanol Industrial Ethanol WaterMethodThe idea to do the try out the way described is due to knowledge from past e xperiments and the IB textbook.Follow these steps 10 measure, five times for each alcohol. rate 1 flier 50cm3 of alcohol in a measuring cylinderStep 2 Weigh and record the empty spirit burnerStep 3 Fill the 50cm3 of alcohol in the spirit burnerStep 4 Weigh and record the filled spirit burnerStep 5 Measure 100cm3 of Water in a measuring cylinderStep 6 Fill the water system into the coat canStep 7 Set up the Apparatus as displayed (1 draught shield in each direction, south, north, west and east, forming a box around the apparatus assure there are 2cm of lieu between the bottom of the metal can and the cotton wick)Step 7 Record the initial temperature of waterStep 8 Light the cotton wick of the spirit burnerStep 9 Record the temperature any 15 seconds until the cotton wick loses its flameStep 10 Weigh the spirit burner with the remaining alcohol to calculate how many grams of alcohol have been usedVarables Temperature Temperature of Water will be measured sooner every experiment. The whole experiment takes place at room temperature. Volume of Water 100cm3 Mass of alcohol 50cm3 filled in spirit burner. The mass will be measured before and after the experiment to figure how much has been used. Time record every 15 seconds Concentration of alcohol 1M Surface heavens of metal can which flame is heating up same cans will be used and positioned at same place above the cotton wick to keep this constant. Length of cotton wick 0.5cm blank space from cotton wick to bottom of metal can 2cmHazard Warnings Industrial Ethanol Highly flammable. Therefore wear gloves and safety spectacles Bioethanol Highly flammable. Therefore wear gloves and safety spectaclesChemistry HL Plan of Investigation
