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 higher temperatures, the gas cannot be liquefied by pressure alone. At the critical point, defined by a critical temperature T<sub>c</sub> and a critical pressure p<sub>c</sub>, phase boundaries vanish. Other examples include the liquid–liquid critical points in mixtures.

在热力学中,临界点(或临界状态)是相平衡曲线的终点。最突出的例子是液-汽临界点,即压力-温度曲线的终点,它指明了液体和其蒸汽可以共存的条件。在较高的温度下,气体不能单靠压力液化。在由临界温度Tc和临界压力Pc定义的临界点,相边界消失。其他例子包括混合物中的液-液临界点。
