Answer from: SkyDoki

Explanation:

A physical change is a change that is characterized by the following

easily reversibleno new substance is formedcannot be represented by a chemical reaction

A chemical change is a change that is characterized by the following

not easily reversible new substances are formed in most cases, they can represented by a chemical reaction

Physical property of a substance is a property that can be seen without changing the identity of the substance while chemical property is a property that describes the changes a substance can possibly undergo to form a new substance.
