Question

What is physical change?​

Answer 1

Answer:

A physical change is a change to the physical—as opposed to chemical—properties of a substance. They are usually reversible.

Examples of physical change include changes in the size or shape of matter. Changes of state—for example, from solid to liquid or from liquid to gas—are also physical changes. Some of the processes that cause physical changes include cutting, bending, dissolving, freezing, boiling, and melting.
