Solved [True False] * Latent heat transfer occurs when - Chegg * A parcel of air is saturated when the amount of water vapor molecules evaporating equals the amount of water vapor condensation in a parcel or air (temperature pressure held constant) *As air cools, the movement of vapor molecules slow and coalesce on condensation nuclei
Meteorology Chapter 4 Flashcards - Quizlet What will occur if a glass of water at a stable temperature is surrounded by saturated air? Condensation is more likely to happen when air ____ and the speed of water molecules _____ The air temperature equals the wet-bulb temperature What happens when air is saturated?
Chapter 4 Water Vapor - University of Colorado Boulder Saturation vapor pressure (es): The pressure that would be exerted by water vapor molecules if the air were saturated with vapor at a given temperature (Units: mb) How does saturation vapor pressure change as temperature changes? Why does this relationship between saturation vapor pressure and temperature exist?
Chapter 4: Water Vapor – Atmospheric Processes and Phenomena When the partial pressure exerted by water vapor is equal to the saturation vapor pressure, the air is saturated The Clausius-Clapeyron equation gives the approximate relationship between saturation vapor pressure (es) and temperature in the atmosphere
Saturation of air with water vapor - University of Arizona The air is saturated in both glasses but there is more water vapor in the warm glass The fact that the rates of evaporation and condensation are equal when air is saturated (RH = 100%) is something we'll be using later when we study the formation of precipitation
Chapter 4 - Moisture Atmospheric Stability Vapor Pressure Saturation Pressure - caused by change of momentum of molecules as they hit a surface; Vapor pressure - that part of the total atmospheric pressure that is due to its water vapor content; Saturation - number of molecules evaporating = number condensing; Saturated vapor pressure - pressure when the air is saturated (cannot hold
Chapter 4 - Vapor pressure is the pressure exerted by water vapor molecules Increases with increasing temperature - Similarly, when air is saturated, the pressure exerted by water vapor molecules is called Saturation Vapor Pressure
Chapter 4 Water Vapor - Atmospheric and Oceanic Sciences Saturation: A condition in which the number of water molecules evaporating from a liquid surface is exactly balanced by the number of water molecules that are condensing
Meteorology Chapters 4-6 Flashcards - Quizlet Saturation is best defined as: A Equal numbers of water molecules evaporating from and condensing into a water surface B A vapor pressure greater than 1000mb C The point when water molecules completely stop evaporating from a water surface D A mixing ratio of at least 100g kg
4. 0: Vapor Pressure at Saturation - Geosciences LibreTexts 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 Liquid-water temperature controls the rate of evaporation, and humidity (water-vapor concentration in air) controls the rate of condensation
