Water vapor, often known as water vapour or aqueous vapor, is the gaseous phase of water. It is a kind of water in the hydrosphere. Water vapor can be formed through the evaporation or boiling of liquid water, or by the sublimation of ice. Water vapor, like the majority of the atmosphere’s elements, is transparent. Water vapor is continually produced by evaporation and eliminated by condensation under normal atmospheric conditions. It is less dense than most other air components and causes convection currents, which can lead to clouds.
