1.1 understand the arrangement, movement and energy of the particles in each of te three states of matter: solid, liquid and gas

Solid

- particles touch
- particles have little energy
- particles do not move much (vibrate a little)

Liquid

- particles touch
- particles have more energy than solid (but less than gas)
- particles move over each other but are always touching at least one other particle

Gas

- particles are not touching, though they may frequently collide
- particles have a great amount of energy
- they move a lot
