1.2 understand how the interconversions of solids, liquids and gases are achieved and recall the names used for these interconversions

Solid > Liquid
This process is called melting: you apply heat.

Liquid > Solid
This is freezing. You remove heat.

Liquid > Gas
Heat is added. The process is evaporation.

Gas > Liquid
Removed heat: condensing.

Diagrams are helpful to understand this concept. Be aware that you don't need to know the process between solid and gas/ gas and solid.
