1. Chapter 3- States of Matter Things are made up of 1 of 4 states: 1. Solid 2. Liquid 3. Gas 4. Plasma

2. Characteristics of Each 1. Solids ► Shape and volume (size) don’t change (definite) ► Particles are packed close together (most dense)

3. 2. Liquid ► Volume (size) does not change ► Shape does change (depends on container) ► Particles not as close together

4. 3. Gas ► No shape (depends on container) ► No volume ► Particles furthest apart (least dense)

5. 4. Plasma ► Not a S,L, or G ► Charged particles ► Found in sun and other stars (99% of universe) ► In the “Best Buy” store ► Car repair shops

6. Take a Look Inside

7. Particles Move ► Solids- vibrate but don’t move much ► Liquids- move but stay close together ► Gases- move quickly and push outwards ► Gases, Liquids, and Solids Gases, Liquids, and Solids Gases, Liquids, and Solids

10. Phase Change Graph ► Adding heat to a material will eventually change it from a solid to a liquid to a gas ► Temp. goes up (gets higher), but it is NOT consistent ► Graph temp. and time data
