... tables. All of this would allow me to find out, hopefully, which is the most efficient fuel and which one is a better burner. Background Knowledge and research: I have some background knowledge of alcohols and how energy is transferred in reactions from previous chemistry experiments, but mainly in Physics. All pure alcohols are composed only of Hydrogen, oxygen and Carbon molecules, and it is because of this high Hydrogen content that they burn so well. The only thing that changes the alcohols is the number of these molecules so alcohols like Ethanol, which is C2H5OH, should burn not nearly as well as Octan-1-ol, which is C8H17OH because Octan-1-ol has more molecules. The number of molecules is directly proportional to the amount of heat produced when burnt because the more bonds are broken by heat the more the more energy given off when they are broken. In Physics I have learnt about ...
