Critical point in phase diagram
Web6.3. Critical Points ... Likewise, there is no point in the phase diagram at which the liquid phase does have these symmetries. That is why the change from one to the other must always involve an abrupt transition in which the symmetry is formed or destroyed. In contrast, since the liquid and gas phases have identical symmetry groups, you can ...

WebFor many physicists, the most interesting feature of this phase diagram is not the diversity of phases but the remarkable behavior near the so-called called critical point at about the coordinate ( Tc, pc) ≃ ( 650 K, 22 MPa) where the phase boundary between the liquid and vapor state suddenly ends at the red dot. WebUsing the phase diagram for water, we can determine that the state of water at each temperature and pressure given are as follows: (a) solid; (b) liquid; (c) liquid; (d) gas; (e) solid; (f) gas. Check Your Learning What phase changes can water undergo as the temperature changes if the pressure is held at 0.3 kPa? If the pressure is held at 50 kPa?

The simplest phase diagrams are pressure–temperature diagrams of a single simple substance, such as water. The axes correspond to the pressure and temperature. The phase diagram shows, in pressure–temperature space, the lines of equilibrium or phase boundaries between the three phases of solid, liquid, and gas.
