1 Answer

Answer :

Answer: A physical property is a characteristic of a substance that can be observed or measured without changing the chemical composition of the substance, while a chemical property is a characteristic that describes how a substance interacts with other substances to form new substances with different chemical properties. For example, density is a physical property, while flammability is a chemical property.
