A change of state occurs when water cools or heats up.
- Melting occurs when ice is heated and it turns into water.
- Freezing occurs when water cools and turns into ice. Water freezes at 0 ºC. This is its freezing point.
- Evaporation occurs when water heats up and turns into water vapour.
- Condensation occurs when water vapour cools and turns into liquid water.
