Abstract

In this document, conventional entropies for several substances are calculated using the third law of thermodynamics and heat capacity data. Students explore the contributions of different phases to the total entropy of a substance by integrating the heat capacity within each phase and adding the individual entropy components together with the phase change contributions.
