Two Phase Gas – Liquid Systems, Phase Rule and Vapor-Liquid Equilibria topics include: Partial saturation terminology, partial saturation material balance problems, gibbs phase rule and vapor liquid equilibria in binary systems. A two-phase mixture of gas and liquid is univariant, meaning it has a specific vapor pressure at a given temperature. If the pressure is reduced by increasing the volume, the material will move from the liquid to the vapor phase to maintain the pressure. The phase rule states that F = C − P + 2, where F is the degrees of freedom, C is the number of components,...

A two-phase mixture of gas and liquid is univariant, meaning it has a specific vapor pressure at a given temperature. If the pressure is reduced by increasing the volume, the material will move from the liquid to the vapor phase to maintain the pressure. The phase rule states that F = C − P + 2, where F is the degrees of freedom, C is the number of components, and P is the number of phases. For example, a sealed flask containing a liquid ethanol-water mixture in equilibrium with its vapor has two degrees of freedom. Vapor-liquid equilibrium is a state of balance where the rates of evaporation and condensation are equal. It occurs when the partial pressure of the vapor phase is similar to the saturation vapor pressure of the liquid phase.
