For a pure substance below the critical pressure, equilibrium liquid–vapour phase change from a saturation state at fixed pressure occurs:
without a change of pressure or temperature
For a pure substance below its critical pressure, equilibrium liquid–vapour phase change at fixed pressure occurs at the corresponding saturation temperature. Added or removed heat changes the phase fraction while pressure and temperature remain constant. Saturation states form a boundary curve; they are not all the critical point.
