This page explains that the four physical states of water — gas, vapour, liquid, solid — apply equally to Volkswagen Golf Mk7 air conditioning refrigerants, the foundation for understanding how the whole system works.
| The four known physical states of water also apply to air
conditioning refrigerants. |

| 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. |

Physical basics — Volkswagen Golf Mk7
What physical states does the Golf Mk7 AC manual describe?
Gas (invisible vapour), liquid, solid (ice/frost) and the phase transitions between them — all applied to understanding how AC refrigerant works.
Every material consists of a mass of moving molecules. The fast moving
molecules of a warmer material loose part of their energy to slower molecules
possessing less heat. This slows down the molec ...
