Sam Forshaw Calculating the ?Hc of the combustion of alcohols. Aim: To work out the ?Hc of the alcohols: ethanol, methanol, pentan-1-ol, butan-1-ol and propan-1-ol by using calorimetry. The idea in this experiment is that if you burn a substance to heat water there is a link between the rise in temperature of the water and the amount of energy the substance contains. For this you need to know the amount of the substance you have burned and the volume and mass of the water you are heating. For this experimant I wil use a copper container for the water, place an aluminium lid on top (to prevent heat loss) and a spirit lamp containing the alcohol that I will be burning. There are however problems with this experiment. Not all of the heat from the reaction will go into the water, much of this energy will be lost to the surroundings and the...
