Investigating the enthalpy change of different alcohols Method In this investigation I am going to try to find out if there is a relationship between different lengths of alcohol chains and their combustion enthalpy change. I am going to do this by using spirit burners and a calorimeter. I will burn the fuel until it has heated up the water in the calorimeter until it is a certain temperature, then I can use the heat capacity of the water and the molecular formula of the alcohol to work out the enthalpy change. Here is my draft method: Equipment: * Aluminium can to act as calorimeter, about 10cm in diameter and able to hold about 200ml of water. * 0-50?c thermometer (or 0-110?c if 0-50?c not available). * 200ml measuring cylinder. * Spirit burners containing: Methanol Ethanol Propan-1-ol Butan-1-ol * Balance (accurate to 2 decimal places). * Clamp stand, clamp, heat mats. Set-up: ...
