Matter

1. Classifying matter by composition

2. States of Matter

2.1. Solid- molecules packed densely together

2.2. liquid- molecules are freer than in solids

2.3. Gas-indefinite shape, volume, easily condensed

2.4. Plasma_Indefinite shape and volume, particles become ionized.

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. Properties of matter

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

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