This is a great explanation... but 1 minor note I'd like to add- phase changes (at a given pressure) for many PCMs occur over a range of temperatures. And there is also the phenomenon of hysteresis where melting occurs at 1 temp range while solidification occurs at a lower range. So a material's state at a given temp near the MP can be dependent on what state it started in.
