A change of state, also known as a change of phase, is when a substance changes from one state of matter to another, such as changing from a liquid to a gas. A phase change is always associated with a change of heat, where the heat is either going into the substance or leaving the substance. Types of phase changes are melting, freezing, vaporization, condensation, and sublimation.
