Well look at the typical heat versus time profile when we heat a pure substance....
Explanation:
The profile (fancifully!) tracks the transition solid to liquid to gas....and while it is clearly an artefact (i.e. made up, not drawn from actual data), it does represent the temperature profile of several phase transitions....
At a phase transition, the temperature remains more or less constant, and does not rise during the equilibrium phase, when there is solid/liquid or liquid/gas equilibrium. The heat pumped into the material at these transitions is conceived to supply the energy required to break apart the condensed phase, and these are respectively the
