Y7 Particles and change of state

What happens to particles during changes of state between solid and liquid.

• Particles move so fast they break from their fixed position.

• Particles melt and become a liquid.

• Particles find a circular orbit around an atom's nucleus.

• Particles stop vibrating and change into their liquid form.
