What is phase equilibrium?

PHASE EQUILIBRIUM IS THE STUDY OF THE EQUILIBRIUM WHICH EXISTS BETWEEN OR WITHIN DIFFERENT STATES OF MATTER, NAMELY SOLID, LIQUID AND GAS. EQUILIBRIUM IS DEFINED AS A STAGE WHEN THE CHEMICAL POTENTIAL OF ANY COMPONENT PRESENT IN THE SYSTEM STAYS STEADY WITH TIME. How do you find phase equilibrium?

How do you know if an equilibrium is stable?

An equilibrium is said to be stable if small, externally induced displacements from that state produce forces that tend to oppose the displacement and return the body or particle to the equilibrium state. Examples include a weight suspended by a spring or a brick lying on a level surface.

What is equilibrium vapor pressure?

The pressure exerted by a vapor in dynamic equilibrium with a liquid is the equilibrium vapor pressure of the liquid. If a liquid is in an open container, however, most of the molecules that escape into the vapor phase will not collide with the surface of the liquid and return to the liquid phase.

What is the equilibrium between water and steam?

…both water and steam in equilibrium with each other at pressure P, and the cylinder is held at constant temperature T, as shown in the figure. The pressure remains equal to the vapour pressure Pvap as the piston moves up, as long as both phases remain present.
