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.

A -  Heat absorption
B -  Heat dissipation
