Matter

1. Properties of matter

1.1. Extensive Properties- depends on the amount of matter present in a sample.

1.2. Intensive Properties-depends on the type of matter (not amount)

2. Classifying matter by composition

3. Changes in matter

3.1. Physical Property- a quality or condition of a substance that can be observed without changing the substane's identity

3.1.1. Physical Change- changing the form of a substance without changing the identity(composition

3.2. Chemical property- a ability of a substance to undergo changes identity through chemical reaction

3.2.1. Chemical change- change that produces matter with a different identity then the original matter

4. States of Matter

4.1. Solid- molecules packed densely together

4.2. liquid- molecules are freer than in solids

4.3. Gas-indefinite shape, volume, easily condensed

4.4. Plasma_Indefinite shape and volume, particles become ionized.
