Chemistry Coursework - Combustion of Alcohols Aim: To find out the amount of energy released when burning different alcohols. Hypothesis: I predict that octan-1-ol will release the most heat energy. This is because there is more bond energy in that molecule than the other alcohols. Within a molecule there are bond energies that are holding the atoms together. When the fuel combusts a chemical reaction takes place, this breaks the bonds, this requires energy, and makes new bonds this gives out energy. The energy differences between the two tell us how much energy was given out or taken in. We can show this on a graph. Planning: In this investigation I will be burning alcohols to heat up a can of water. I will be burning seven alcohols, Ethanol, Propan-1-ol, Butan-1-ol, Pentan-1-ol, Hexan-1-ol, Heptan-1-ol, Octan-1-ol. The aim is to find out how much energy is produced when burning these alcohols. 'An alcohol...
