Investigation to Find the Relative Energy Release of Five Alcohols: Eth

Investigation to Find the intercourse Energy Release of Five Alcohols Ethanol, Methanol, Propanol, Butanol and PropanolAimIn this experiment I give investigate to see which alcohol unloosensthe almost energy during breakion Methanol, Ethanol, Propanol,Butanol or Pentanol.HypothesisI hazard that the alcohols with the longest carbon chains will press releasethe most energy. This is because when a bond is broken energy isreleased. This means that the alcohols with longer chains and therefore to a greater extent bonds will release much energy. This will mean theywill heat the water quickest. This should mean that Pentanol will heatthe water by the largest mount in 5 minutes. However, because of thelonger hydrocarbon chains and therefore more bonds, Pentanol will alsobe the hardest to ignite, least volatile and least viscous. contempt the larger requirement for in establish of energy, the amount createdby the breaking of bonds should summation by more which will mean thatPentanol will still release more energy than Methanol, Ethanol,Propanol and Butanol. To test this I find performed several(prenominal)calculations. By using figures for the amount of KJ/mol that thebreaking of various bonds (O-O, C-H, O-H, C-C, C-O) release I dupecalculated the amount of energy that is needed to combust each of thealcohols. GRAPHThe calculations that I have performed have proved my possible action to becorrect. Pentanol is quite clearly the alcohol that should releasemore energy, more than five times as much as Methanol, but myexperiment will show whether this extra energy can be put to good use,or if too much is wasted for it to be useful.The calculations show that Pentanol will release more energy. Eventhough the combustion product... ...could have effected the amount of alcohol that was getting to thetip of the wick to be burnt. Also, the wicks were made of many various materials. Although the wick itself does not burn thedifferen t materials may have soaked up more of the alcohols allowingthem to burn easier.However, I do think that the method that we developed was the best waythat we could have done the experiment. The overall method was verysuccessful and allowed us to perfect(a) the experiment efficiently.However, I would quite like to repeat the experiment. I would decidedly try to change the method so that the experiment is in amore controlled environment. This would prevent several factors, suchas the wind, from effecting or results as they did in this experiment.Overall the experiment was relatively successful and provided us witha fairly useless, but interesting, set of results.
