The same element has different physical properties in different phases or in different compounds. Chemical properties describe a substance's ability to react and form new substances. They can only be tested by reacting the material with other things to see how it changes.

Physical properties include color, density, hardness, and melting and boiling points. A chemical property describes the ability of a substance to undergo a specific chemical change. To identify a chemical property, we look for a chemical change.
