Abstract

Ehrenfest classification of phase transitions discerns between two categories: first-order transitions obeying Clapeyron equation and second-order transitions that should obey Ehrenfest equations. Considering the equilibrium phase diagram of binary systems with lentiform two-phase field and with bell-shaped miscibility gap, the corresponding Ehrenfest equations applicable for calorimetry and dilatometry are derived.
