Identifying Matter You use physical properties to identify matter.
Density Density is the amount of matter in a given space, or volume. The two balls below have different densities.

Comparing Physical and Chemical Properties You can observe physical properties without changing the identity of the substance. Chemicals properties are more difficult to observe.
Characteristic Properties The properties that are most useful in identifying a substance are characteristic properties.

Chemical Changes and New Substances
What Happens During a Chemical Change? During a chemical change a substance changes chemical properties.
Signs of Chemical Changes Some common signs of chemical changes includes a change in color, odor, production of heat, fizzing, and so on.
Matter and Chemical Changes Chemical changes change the identity of the matter involved.

Physical Versus Chemical Changes
A Change in Composition Physical changes do not change the composition of a substance while chemical changes do.
Reversing Changes Many physical changes are easily reversed, but most chemical changes cannot easily be reversed.
