Different quantities of water are heated with a heating coil in a calorimeter. The quantities of water were chosen to match the size of the calorimeter (100 ml, 150 ml, 200 ml) and are directly related to each other so that the following becomes obvious:
the greater the quantity of water, the longer it must be heated. Or: for the same heat energy the temperature increase is inversely proportional to the quantity of water. The water is heated with a heating coil to ensure that all three experimental runs are conducted with the same calorific input. If a butane burner with an equally large flame were to be used for each run, this requirement would generally not be fulfilled since the temperatures of - e.g. - the support ring, the wire gauze and the beaker have an influence on the measuring results.
