Phase Transition Data for the Elements

Phase Transition and Other Data for the Elements

In physics, a phase transition (or phase change) is the physical process of transition between one state of a medium and another. Commonly the term is used to refer to changes among the basic states of matter: solid, liquid, and gas, and in rare cases, plasma.

Where:

M = molecular weight
T_m = normal melting temperature,
Δh_fus = enthalpy (or latent heat),
T_b = normal boiling point temperature
Δh_vap = enthalpy (or latent heat) of vaporization,
T_c = critical temperature,
P_c = critical pressure,
T_tr = transition temperature
