Water - Saturation Pressure vs. Temperature
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. WebDec 9, 2024 · During the equilibrium state (i.e., at saturation) there is a balance between the rate of evaporation from the liquid and the rate of condensation from vapor.

Vapour pressure Definition & Facts Britannica
WebIn the month of January, the saturated vapor pressure may be anywhere around 4 millibars, but in the month of August, it may be 10 millibars or more. This disparity arises from the fact that warmer air is capable of holding a greater quantity of water vapor than air at a lower temperature. *. The pressure that is exerted by a vapor when it is ... Vapor pressure (or vapour pressure in English-speaking countries other than the US; see spelling differences and equilibrium vapor pressure) is defined as the pressure exerted by a vapor in thermodynamic equilibrium with its condensed phases (solid or liquid) at a given temperature in a closed system. The equilibrium vapor pressure is an indication of a liquid's thermodynamic tenden… WebDec 1, 2024 · The vapor pressure of water decreases as the temperature decreases; the vapor pressure of water at room temperature does not exceed 0.0313 atm. Water begins to boil when its vapor pressure is ... gutter clips for xmas lights screwfix
