Describe the process of water changing state

Water freezes into ice heats up and boils to steam

Substances can change state, usually when they are heated or cooled.

The closeness, arrangement and motion of the particles in a substance change when it changes state.

If water turns to gas, (for example steam) the particles move more freely with each other and if it turns to solid (ice) the particles are packed more closely together.

To change into gas, water needs to be heated and to change into a solod water needs to be freezed
