The atmosphere is composed of 20% oxygen, 79% nitrogen, and other gaseous particles and water vapor. Each component exerts some of its pressure on the surrounding environment, collectively called atmospheric pressure, and is measured in Pascals (units Pa). The atmosphere is basically a stable whole except for water vapour, which is constantly changing with weather conditions, especially in relation to temperature. As free water evaporates into the air, the pressure of the water vapor in the atmosphere increases, creating a barrier against more water vapor entering the air. Air in enclosed spaces, in particular, is rapidly saturated with moisture at a given temperature, and the vapor pressure created by the atmosphere prevents further evaporation of free water.
