Section 2Physical Properties Chapter K1 Physical Properties, continued • 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.
Section 3Chemical Properties Chapter K1 Chemical Properties • 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.
