A physical change involves altering physical properties without changing the chemical composition of a substance, resulting in a reversible process that does not create new substances.
A physical change occurs when a sample of matter changes one or more of its physical properties without affecting its chemical composition. For example, melting ice or boiling water are physical changes where the substance changes state without becoming a new substance.
During a physical change, the arrangement of particles may alter, but the chemical composition remains the same. This type of change is reversible and does not result in the creation of a new substance.
