9.2.7.1 Basic Definitions Critical temperature (T c)The maximum temperature at which a gas can be converted into a liquid by an increase inpressure. Critical pressure (p c)The minimum pressure which would suffice to liquefy a substance at its criticaltemperature. Above the critical pressure, increasing the temperature will not cause a fluidto vaporize to give a two-phase system.
In thermodynamics, a critical point (or critical state) is the end point of a phase equilibrium curve. The most prominent example is the liquid-vapor critical point, the end point of the pressure-temperature curve that designates conditions under which a liquid and its vapor can coexist. At the critical point, defined by a critical temperature T c and a critical pressure p c, phase boundaries vanish. Other examples include the liquidâliquid critical points in mixtures.
