Answer: Water vapour, also known as water vapour or aqueous vapour, is the gaseous state of water. It is a type of water in the hydrosphere. Water vapour can be created by evaporating or boiling liquid water or sublimating ice. Water vapour, like the majority of atmospheric constituents, is transparent. Water vapor is continuously produced by evaporation as well as eliminated by condensation under normal atmospheric conditions. It’s much less thick than most other air constituents and causes convection currents, which can lead to clouds. Humidity relates to the quantity of water vapour in the air. Relative humidity is the proportion of moisture in the atmosphere, particularly in comparison to its maximum capacity at a specific temperature. Hygrometers are devices that measure the vapor content of the air.
