Synonym: 000 = Vapour Liquid Equilibrium (VLE)
A state of Thermodynamic equilibrium between the liquid and gas state of a Fluid Mixture.
The PT diagram for Pure Substance will see Vapour Liquid Equilibrium (VLE) as a set of points along a smooth curve ending up with a Critical Point
(T_c, p_c) (see Fig. 1).
The PT diagram for Fluid Mixture will see Vapour Liquid Equilibrium (VLE) as a closed area with a junction at Pseudo-Critical Point (T_{pc}, p_{pc}) (see Fig. 2).
