What are physical properties?

Back

Physical properties are characteristics of a substance that can be observed or measured without changing the substance's identity, such as color, density, and melting point.

What are chemical properties?

Back

Chemical properties describe a substance's ability to undergo changes that transform it into different substances, such as reactivity with acids or flammability.
