What is a Property?

A property is a characteristic that

describes an object or a substance.

All matter can be described based on its

physical properties and its chemical properties.

Physical properties are characteristics that can be observed without changing the identity of

the object or substance.

Examples of Physical Properties Include:• Color• Texture• Hardness• Density• Flexibility• Freezing Point• Melting Point• Boiling Point

Chemical properties are characteristics that can be observed as a result of a chemical reaction. A chemical reaction always

results in a change to the substance that is reacted on.
