Final answer:

A physical change involves altering the physical properties of a substance without changing its chemical composition.


Explanation:

A physical change occurs when a sample of matter changes its physical properties without altering its chemical composition. For instance, melting a solid, boiling a liquid, or sublimating a gas are all examples of physical changes. During a physical change, the arrangement of particles may change, but the identity of the substance remains the same.
