The process when chemical substance is changing its phase form.
The most popular example is chemical substance changes from one state of matter to another:
| Gas | Liquid | Solid | Plasma | |
|---|---|---|---|---|
| Gas | – | Condensation | Deposition | Ionization |
| Liquid | Vaporization | – | Solidification / Freezing | – |
| Solid | Sublimation | Melting | – | – |
| Recombination | – | – | – |
