Concept Introduction:

• Phase change refers to change in physical state of a substance.  If a substance undergoes change in its physical state from one physical form to another physical form, then the substance is said to be undergone phase change.
• Phase diagram illustrates temperature and pressure conditions at which a substance can remain stable at a certain physical state. The distinct separation between the different phases of a system is known as phase boundary.
