摘要

The construction and operation of an evaporation calorimeter for determining the mean specific heat at constant pressure (Cp) for solids in the range 80-298K is described.  The calorimeter comprises two Dewar flasks, one located within the other and each partially filled with liquid nitrogen. The specific heat is calculated from a knowledge of the volume of nitrogen gas evolved following the introduction of a sample of solid into the inner Dewar.
