Answer
A phase diagram summarizes when a substance exists as a solid, liquid and gas. It is a plot of substance's pressure and temperature under different conditions.
The relationships among the phases of a single substance are illustrated by a phase diagram. Phase diagrams enable us to predict changes in the melting point and boiling point of a substance as a result of changes in the external pressure; we can also anticipate directions of phase transitions brought about by changes in temperature and pressure.
