[#334] Water vapour is:
Correct Answer

(A) A gas

Water vapour can be produced from the evaporation or boiling of liquid water or from the sublimation of ice. Unlike other forms of water, water vapour is invisible. Under typical atmospheric conditions, water vapour is continuously generated by evaporation and removed by condensation. It is less dense than air and triggers convection currents that can lead to clouds.
