What happens to substances or materials that undergo physical and chemical changes? That depends on which change. Physical changes may result in a change in appearance, but never a change in composition. Ripping, folding, melting, boiling, dissolving, and câ¦rumpling are examples of physical changes.

Examples of this are burning and reacting with acid.
