WebThe effect of water vapor is evident within an air mass. Parcels of air that contain water vapor within a drier air mass are more buoyant and tend to have less air pressure and tend to rise. You can see evidence of this on a sunny day by looking at the scattered cumulus clouds. These clouds are a result of a parcel of air that are moister ... http://pressbooks-dev.oer.hawaii.edu/atmo/chapter/chapter-4-water-vapor/

Evaporation is a type of vaporization that occurs on the surface of a liquid as it changes into the gas phase. High concentration of the evaporating substance in the surrounding gas significantly slows down evaporation, such as when humidity affects rate of evaporation of water. When the molecules of the liquid collide, they transfer energy to each other based on how they collide. When a … WebLower temperature air cannot contain as much water vapor as higher temperature air.

I believe this is how 'freeze drying' works. The rate at which evaporation of liquid water occurs is a function of the water's temperature and the vapour pressure above the liquid water. The vacuum pump boils the water by removing the vapour pressure.

WebHeat can temporarily reduce relative humidity but it does not remove moisture from the air and, most importantly, it does not reduce vapor pressure. In fact, heating the space with particular types of heat-only systems, such as direct-fired heaters, will actually add moisture to a space as combustibles such as propane or natural gas are burned.
