Investigation to Find the Relative Energy Release of Five Alcohols: Ethanol, Methanol, Propanol, Butanol and Propanol Aim: In this experiment I will investigate to see which alcohol releases the most energy during combustion; Methanol, Ethanol, Propanol, Butanol or Pentanol. Hypothesis: I think that the alcohols with the longest carbon chains will release the most energy. This is because when a bond is broken energy is released. This means that the alcohols with longer chains and therefore more bonds will release more energy. This will mean they will heat the water quickest. This should mean that Pentanol will heat the water by the largest mount in 5 minutes. However, because of the longer hydrocarbon chains and therefore more bonds, Pentanol will also be the hardest to ignite, least volatile and least viscous. Despite the larger requirement for input of energy, the amount created by the breaking of bonds should increase by more which will...
