I think this question is seeking a differentiation between physical and chemical changes. An example of physical change is when hot water is poured over an ice cube. The ice rapidly turns back into liquid. Physical changes make matter take a different form: size, shape, color.

Also, physical changes occur when substances are mixed but don't chemically react. No new substance is created during a physical change. This is what happens in a chemical change.

A physical change occurs when something changes but keeps the same chemical composition. The physical change involves a state of matter and energy. No new substance is created during the physical change, although matter takes on a different form. Physical changes also occur when substances are mixed but don't chemically react.

It is the process by which a substance goes from one physical state to another. This involves solids, liquids, and gases. A material can go from a solid to a liquid, or a liquid to a solid, and so on. Some instances of physical change include ice melting into liquid, alcohol evaporating, iron rusting and salt water.
