Detailed explanation-1: -A physical change is a change in one or more physical properties of matter without any change in chemical properties. 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.

Detailed explanation-2: -Common physical changes include melting, change of size, volume, color, density, and crystal form.

Detailed explanation-3: -The change of state of a substance does not involve the formation of new molecules. A change in temperature or pressure can reverse the change in state. Therefore, a change in state is a physical change.

Detailed explanation-4: -Changes in the size or form of matter are examples of physical change. Physical changes include transitions from one state to another, such as from solid to liquid or liquid to gas. Cutting, bending, dissolving, freezing, boiling, and melting are some of the processes that create physical changes.
