WebIf the water vapor pressure in the air is 10.3 mbar, the vapor saturates on a surface with 45 o F (7 o C). Note! The atmospheric pressure of air is 1013 mbar (101.325 kPa, 760 mmHg). As we can see the maximum water vapor pressure - the saturation pressure - is relatively small. Example: Relative Humidity and Vapor Pressure 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.

What is Vapour Pressure? - Definition, Raoult
WebThe equilibrium vapor pressure between water vapor (to the right of the line) and liquid water (to the left of the line) as calculated by the Clausius–Clapeyron Equation. The line for liquid water can be extended below 273 K, the freezing point, because water can remain liquid at those low temperatures and become a “supercooled” liquid. WebJan 5, 2024 · The vapor pressure of water is the point of equilibrium between the number of water molecules moving between the liquid … WebA liquid’s vapor pressure is directly related to the intermolecular forces present between its molecules. The stronger these forces, the lower the rate of evaporation and the lower the … overly punctual
