When substances undergo phase transitions such as melting, boiling, sublimation, the entropy changes. The calculation of this entropy change is straightforward since the process occurs at constant temperature and pressure. Two parameters are needed: the enthalpy and the temperature of the transition.

In a two-phase region of a phase diagram, such as solid+liquid, we can determine the composition of each phase from horizontal tie-lines and their intersection with the solidus and liquidus lines. We can also see evidence of a solubility limit by examining lattice parameter as a function of composition. If it's linear across the composition ...
