Chemistry Coursework: Comparing the Enthalpy Changes of Combustion of Different Alcohols

Background

The enthalpy (energy) change of combustion, or as it is known in its shortened form ?Hc is the enthalpy change that occurs when 1 mole of a fuel is burned completely in oxygen. For standard enthalpy change of combustion to take place the fuel needs to be burned in standard conditions i.e. 1 atmosphere pressure and 298K. Of course this is more theoretical as carrying out a combustion experiment without any heat loss is very difficult. In the experiment I am carrying out I will not be able to achieve standard conditions for combustion due to limitations with equipment. A way of minimising the heat loss during an experiment to measure the enthalpy change of combustion is by using a bomb calorimeter to maximise the amount of heat trapped during the combustion and afterwards.

Below: Diagram of a bomb calorimeter:
