- Particles in a random position
- Particles are close together
- Slide past each other
- No definite shape
- Definite volume
- Cannot compress
- Flows

- Particles are spread out
- Particles in random position
- Particles move quickly
- Move in all directions
- No definite shape
- No definite volume
- Can be compressed
- Flows
Change of state
Ā 
Example:
- Ice => Water => Water vapour
<<^^Cold^^<<
- particles get closer together
- losing heat energy
[[Heat[[
- particles get closer together
- more heat energy
