Principle
The dependence of heating a liquid on its specific heat capacity
should be established in this experiment. In these
experiments, the liquids' masses and their thermal input are the
same. Thus, the specific heat capacities obtained are not absolute,
but can be given in relation to water. The liquids are heated
with a heating coil to ensure that each experiment is conducted
with the same thermal input. If a butane burner with
a constant flame were to be used, this condition 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.
Benefits
