... quickly in a tin as tin is a better conductor of heat. I have decided to use two fairly close distances from the flame. I will be taking results from the difference of five and ten centimetres as there are distinct differences in temperature with these distances. I also attempted a twenty centimetre gap in my preliminary experiments but this was too far and there was very little temperature rise. I decided to use 150 millilitres of water in the beaker for each experiment. I found 100 millilitres of water reached boiling point when heated over the butanol and there was not enough temperature difference with 200 millilitres of water. Only one distance shall be used in the "proper" experiment. This is the table of results I acquired from my preliminary experiments: Alcohol Amount of Water/ml Height/cm Temperature/ ºC Time/min Fuel Used/g Butanol 150 10 26 - 44 2 4.58 150 20 26 - 29 2 4.67 Ethanol 100 10 26 - 51 2 0.91 100 5 26 - 71 2 1.72 Propanol 150 10 26 - 38 2 2.66 150 20 26 - 30 2 2.77 Methanol 150 10 26 - 31 2 2.45 150 5 26 - 34 2 2.12 Safety ...
