1. Phases of Matter

2. States of Matter
Solid
Liquid
Gas
Plasma

3. Sodium as Solid, Liquid, Gas

4. Kinetic Molecular Theory
all matter is composed of small particles
these particles are in constant motion

5. Solid
Definite volume
Definite shape
Particles closely packed together
Strong attractive
forces
Very low KE

6. Liquid
Definite volume, but takes the shape its container
Particles close together
and mobile
Low KE

7. Gas
No definite volume
No definite shape
Particles spaced
far apart
Attractive forces
much weaker
High KE

8. Microscopic view of a gas
Microscopic view of a liquid
Microscopic view of a solid

9. Plasma Gas-like Very high KE
Collide with enough energy to break into charged particles
