In the phase transition of water, a system in which water and water vapor coexist in equilibrium is called saturated. This saturated state has a critical point; the temperature at this critical point is called the critical temperature, which is 374.15 ℃.

The pressure at the critical point is called the critical pressure, which is 22.12 MPa.
