Comparing the Enthalpy Changes of Combustion of Different Alcohol's and fuels Plan Introduction In this experiment I will attempt to find out the energy needed to raise the temperature of 1g of water by 1oC using different fuels and alcohol's. This will enable us to determine the change in enthalpy for the different substances. Method * Firstly I will measure 200cm3 of water out into a copper coulometer * Then I will half fill a spirit burner with the required fuel, the burner must have a lid to stop evaporation * This will be weighed and the weight recorded * I will then set up the apparatus as shown above trying to keep the draft excluder ad need to the experiment as possible to reduce heat loss but not so close as to starve the reaction of oxygen, thus causing incomplete combustion * The water temperature will be recorded and the wick of the burner ignited * After securing...
