When water in its liquid state changes into gas, it is said to have...
Refer to figure.
When liquid water changes into vapour, the process is called evaporation.
| Latent heat is absorbed | |
| Solid to liquid | Melting |
| Solid to gas | sublimation |
| Liquid to gas | Evaporation |
| Latent heat is released | |
| Liquid to solid | freezing |
| Gas to liquid | condensation |
| Gas to solid | deposition |
The latent heat of a substance is the heat absorbed or released without change of temperature when the substance changes state.
- "Sublimed": solid directly to gas (e.g. ice to vapour), skips the liquid phase.
- "Condensed": gas to liquid, the opposite of evaporation.
- "Deposited": gas directly to solid, the reverse of sublimation.
