Expert Answer

Step 1

Phase diagram:

The lines in a phase diagram correspond to the combinations of temperature and pressure at which two phases can coexist in equilibrium. 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. The solid and liquid phases are in equilibrium all along this line; crossing the line horizontally corresponds to melting or freezing. 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.

The line that c...
