Explanation:
Detailed explanation-1: -In a physical change, the form of matter is changed from one form to another but no new substance is formed. Physical changes are reversible in nature and we can obtain the substance back even after the change, hence the changes are temporary.
Detailed explanation-2: -Hence, changes in which new substances are formed are called chemical changes.
Detailed explanation-3: -A change in which a substance undergoes a change in its physical properties such as shape, size, color, and state is called a physical change. A physical change is generally reversible, (some exceptions). In this change, no new substance is formed. Example: An ice cube melting into water.
