The vapour pressure of water is the pressure exerted by molecules of water vapor in gaseous form (whether pure or in a mixture with other gases such as air). The saturation vapour pressure is the pressure at which water vapour is in thermodynamic equilibrium with its condensed state. At pressures higher than vapour pressure, water would condense, whilst at lower pressures it would evaporate or sublimate. The saturation vapour pressure of water increases with increasing tempe… Webis the mixtures total pressure. Nitrogen mole fraction – 78% Oxygen mole fraction – 21% Argon mole fraction – 0.9% b) Relative humidity is the measure of the partial pressure of water vapor in the atmosphere, relative to the saturation vapor pressure of water at that temperature.
