Freezing-In And Chaotization - Two Varieties Of Second-Order Phase Transitions

Thermodynamic description of vitrification restores its consideration as phase transition. Objections raised against such consideration, are based on the erroneous idea of phase transitions, i.e. on sincere conviction that: phase equilibrium exists at a second-order phase transition; transition temperature does not depend on the rate of the change of the temperature of a system; straight and reverse transitions occur without hysteresis. Therefore we consider vitrification as phase transition which occurs not at Tg, but at a lower temperature, Tc.
