The phase diagram is as for type I but with the addition of a three phase (liquid-liquid-gas)line ending at an upper critical end point UCEP and a (liquid-liquid) critical line starting from the UCEP and rapidly approaching high pressures This type can occur with or without azeotropy Type III This phase diagram has two distinct critical
a line of discontinuous transitions terminates at a critical point and the isotherms ex-hibit singular behaviour in the vicinity of this point The phase diagram is simpler in appearance because the symmetry H ??H ensures that the critical point occurs at H c = M c = 0

What is critical point in phase diagram?
In a phase diagram, 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 Tp and critical temperature Pc. What is high boiling point?
What are the parameters of the critical point of water?
At the critical point the saturated-liquid and saturated-vapor states are identical. The temperature, pressure, and specific volume at the critical point are called the critical temperature, critical pressure, and critical volume. For water, these parameters are the following: Phase diagram of water.
What is the critical point?
The critical point is the highest temperature point on the liquid/gas phase line. Is it true that the particles of a substance are slower and more closely packed in the gaseous phase than in the liquid phase? No, that is not true.
What is the triple point of the water phase diagram?
The water phase diagram has a triple point corresponding to the single temperature and pressure at which solid, liquid, and gaseous water can coexist in a stable equilibrium (273.16 K and a partial vapor pressure of611.657 Pa).
