Know the terms for the changes in state between solids, liquids and gases (gas to solid and solid to gas transfers are not required)

Explain, in terms of the motion and arrangement of particles, the thermal expansion of solids, liquids and gases, and state the relative order of magnitudes of the expansion of solids, liquids and gases

Describe latent heat as the energy required to change the state of a substance and explain it in terms of particle behaviour and the forces between particles
