A 2-phase region on PT Diagram where both liquid and gas state of a Fluid Mixture share the same volume and each occupying a certain percentage of this volume volume (see see Fig. 1).
It forms a closed region bounded Vapour Liquid Envelope is bounded by Bubble Point Curve and Dew Point Curve with a junction at Pseudo-Critical Point
