WebOct 11, 2024 · At this temperature, water releases about 585 cal/g as it condenses. Given the slope of its vapor pressure curve, about 1.1 torr/deg at 20°C, condensation will roughly triple the heat capacity of saturated air, reducing $\gamma$ and the lapse rate until the air has dried out. The effect is even greater in tropical climes, where the altitude of ... WebSince air is a gas, it responds to changes in temperature, elevation, and latitude (owing to a non-spherical Earth). Air pressure decreases naturally as we rise in the atmosphere, or up a mountain, we must make correction to the air pressure owing to elevation above sea level. These corrections are easily made by adding the the air
