Phase changes occur when matter transitions between solid, liquid, and gas states. During a phase change, molecules either absorb or release heat energy as they speed up or slow down. There are several types of phase changes, including melting (solid to liquid), freezing (liquid to solid), vaporization/boiling (liquid to gas), evaporation ...

A common thermodynamic diagram for a hypothetical material is shown in Fig. 8.1a as a map for the three-phase regions related to the general pressure function (P=fleft ( Tright ) ), where T is the temperature. These regions are identified as solid (S), liquid (L), and vapor (V ) phases, which coexist at a fixed pressure–temperature triple point (TP).
