Explanation:

A physical change is a change in the form of a substance. In a physical change, the chemical composition of the substance remains the same. For example, melting ice (solid water) to liquid water is a physical change. The substance is still \(H_2O\), just in a different physical state. A chemical change, on the other hand, results in the formation of new substances with different chemical compositions.
