It is therefore called the triple point of the substance, and it represents the only point in the phase diagram in which all three states are in equilibrium. Point C is the critical point of the substance, which is the highest temperature and pressure at which a gas and a liquid can coexist at equilibrium. The figure below shows what happens when we draw a horizontal line across a phase diagram at a pressure of exactly 1 atm.
A phase transition curve may either intersect two other phase transition curves at a triple point or terminate at a critical point. Phases not in equilibrium, which can coexist with phases in equilibrium, occur in solids as a result of the slowness of the diffusion processes that lead to thermodynamic equilibrium. In this case, the phase rule may not be satisfied.
