This document discusses the differences between physical and chemical changes. Physical changes alter the physical properties of a substance but do not change its chemical composition, such as changes in state from solid to liquid to gas. Chemical changes create new substances through chemical reactions that alter the molecular or atomic structure of the original substances. Examples of both physical and chemical changes are provided.
