The enthalpy change associated with one of these events is called the heat of fusion.
These events in lyotropic liquid crystals are predicted by the hard-rod model. The one-dimensional Ising model lacks these events, unlike the two-dimensional model. Ehrenfest proposed a classification system of these events, which occur at both the Neel [ney-EL] and Curie temperatures. On a pressure versus temperature diagram, they occur when lines of equilibrium are crossed. The enthalpy change associated with one of these events is called the heat of fusion. For 10 points, name these events whose types include sublimation, vaporization, and melting.
