What is Physical Change?

A physical change is a change in a substance's physical properties (such as shape, size, phase, or state of matter) without any change in its chemical composition or molecular structure. Examples include melting ice, boiling water, dissolving salt (the salt can be recovered), and cutting a piece of paper. Physical changes are generally reversible and do not form new substances.
