What term describes water in gas form?

Explanation:
In the gas state, water is called water vapour. This is the general term for water when it exists as a gas, regardless of how it became gas. Steam is the familiar name for hot water vapour produced by boiling, but the precise term for water in its gaseous form is water vapour. The other options describe a process (boiling) or a phase change (melting) rather than naming the substance in its gas state.
