Webatmospheric pressure, also called barometric pressure, force per unit area exerted by an atmospheric column (that is, the entire body of air above the specified area). Atmospheric pressure can be measured with a mercury barometer (hence the commonly used synonym barometric pressure), which indicates the height of a column of mercury that exactly …
WebSaturated vapor pressure (e_s) is influenced by temperature, whereas vapor pressure (e) is influenced by both temperature and the actual amount of moisture in the air. As t emperature increases, the saturation vapor pressure also increases, as more molecules have enough energy to escape into the gas phase. On the other hand, vapor pressure is ...
