In thermodynamics, the triple point of a substance is the temperature and pressure at which the three phases (gas, liquid, and solid) of that substance coexist in thermodynamic equilibrium. For example, the triple point of mercury occurs at a temperature of â38.83440 Â°C and a pressure of 0.2 m Pa.
This is the definition of critical point or critical state in chemistry, along with examples. This is the definition of critical point or critical state in chemistry, along with examples. Critical Point Definition The critical point or critical state is the point at which two phases of a substance initially become indistinguishable from one another. The critical point is the end point of a phase equilibrium curve, defined by a critical pressure T p and critical temperature P c. At this point, there is no phase boundary. Also Known As: critical state. Critical Point Examples
