Combustion of Alcohols THE COMBUSTION OF ALCOHOLS PROBLEM Investigate the heat energy in a range of alcohol's used as fuels. HYPOTHESIS I predict that octanol 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, …

…beaker indicated this. Improvements can be made to this by insulating the sides of the beaker, using a different material for the beaker, using a lid a providing a draught screen as shown below. Alternatively we can remove all faults in planning by using an advanced technique such as a bomb calorimeter. This is the most accurate way of measuring bond energies and this will be as accurate as we can get in our results.
