A Particle model of matter - Far apart from each other

- Use to explains the properties of a solid, a liquid and a gas - Closely packed together (not as close as in solid) - Closely packed together - In fixed position - Vibrate in fixed position

Soli d

- Not arranged in fixed position - Free to move

- Not in fixed position

in all directions

- Free to move in all directions (in short distant)

Liquid

Gas
