Kate McAllister 12 VK Chemistry Coursework Planning assessment- Comparing the enthalpy changes of combustion of different alcohols Aim: I am going to investigate the difference in enthalpy of combustion for a number of different alcohols. My aim is to find out how carbon chain length affects the enthalpy change that occurs during the combustion of alcohols. The enthalpy change of combustion of a fuel is a measure of the energy transferred when one mole of the fuel burns completely in oxygen. I will be able to calculate a value for enthalpy change by burning different fuels to heat a specific amount of water using the fact that 4.2J of energy are required to raise the temperature of 1g of water by 1oC. I will produce a wide range of results and will be able to compare them, calculate their enthalpy change of combustion and effectively find an answer my brief. Apparatus: Spirit burner (75 cm3) 500 ml copper...
