Phase transitions are similar to chemical reactions in that they each have an associated entropy change....
Phase transitions are similar to chemical reactions in that they
each have an associated entropy change. A phase transition involves
the breaking or forming of intermolecular attractive forces.
A change in entropy accompanies not only a variation in the
temperature, pressure, or volume of a system but also a physical
transformation such as the fusion, vaporization, or transition from
one crystalline state into another.
In the equilibrium between two phases, the exchange of heat can
be carried out reversibly, and...
