Phase Equilibrium Boundary on Phase Equilibrium Diagram separating the single-phase liquid region and 2-phase liquid-vapour region on PT Diagram (see Fig. 1).

The slightest pressure drop or temperature increase results in liberation of the first bubble of vapour forming a 2-phase liquid-vapour system.
