A phase change is the reversible physical change that occurs when a substance changes from one state of matter to another. Melting, freezing, vaporization, condensation, sublimation, and deposition are six common phase changes.
Examples of chemical changes are burning, cooking, rusting, and rotting. Examples of physical changes are boiling, melting, freezing, and shredding. Many physical changes are reversible, if sufficient energy is supplied. The only way to reverse a chemical change is via another chemical reaction.
Properties such as shape, size, colour and state of a substance are called its physical properties. A change in which a substance undergoes a change in its physical properties is called a physical change. A physical change is generally reversible. In such a change no new substance is formed.
Physical change is a temporary change. Some examples of physical change are freezing of water, melting of wax, boiling of water, etc. A few examples of chemical change are digestion of food, burning of coal, rusting, etc. Generally, physical changes do not involve the production of energy.
