Volkswagen Golf Service & Repair Manual: Physical basics

The four known physical states of water also apply to air conditioning refrigerants.
1 -  Gas (invisible)
2 -  Vapour
3 -  Liquid
4 -  Solid
 

Physical basics

When water is heated in a container (heat absorption), the rising water vapour is visible. If the vapour is heated by further heat absorption, the visible vapour becomes invisible gas. This process is reversible. If heat is extracted from gaseous water, it changes first to vapour, then to water and finally to ice.
A -  Heat absorption
B -  Heat dissipation
