List Out the General Features of a Phase Diagram

Question

Examlex · Accepted Answer

The Answer is

\bullet

A typical phase diagram consists of discrete regions that represent the different phases exhibited by a substance. Each region corresponds to the range of combinations of temperature and pressure over which that phase is stable.

\bullet

The lines in a phase diagram correspond to the combinations of temperature and pressure at which two phases can coexist in equilibrium.
a. The line that connects points A and D separates the solid and liquid phases and shows how the melting point of a solid varies with pressure.
b. The line that connects points A and B is the vapor pressure curve of the liquid. It ends at the critical point, beyond which the substance exists as a supercritical fluid.
c. The line that connects points A and C is the vapor pressure curve of the solid phase.

\bullet

The point A represents the triple point, which is the only combination of temperature and pressure at which all three forms of matter are in equilibrium, and hence can exist simultaneously.
