Physical Properties Characteristics of a substance that can be observed or measured without changing

Physical Properties Characteristics of a substance that can be observed or measured without changing the samples identity. n Color n Size n Shape n Density n Freezing and Boiling Points We can use physical properties to separate mixtures.

§ Physical properties of matter are categorized as either Intensive or Extensive § Intensive

§ Physical properties of matter are categorized as either Intensive or Extensive § Intensive Properties are properties that do not depend on the amount of the matter present. § § Color Odor Density Boiling point § Extensive Properties are properties that do depend on the amount of matter present. § § Mass Weight Volume Length

Chemical Properties: Characteristics of a substance that indicate whether the sample can undergo a chemical change. § Flammability § Reaction to light

Physical Changes: § No change in identity Examples: melting, boiling, bending, cutting Water Cycle

Physical Changes: § No change in identity Examples: melting, boiling, bending, cutting Water Cycle (State Changes)

Chemical Changes: § involve a change in identity – the formation of a new

Chemical Changes: § involve a change in identity – the formation of a new substance. Also called a chemical reaction. (see light, feel heat, see bubbles, new smell) Examples: rusting, burning…or…. . Watch this…. . http: //youtu. be/1 z. Wyk. Q 8 Xc 6 w
