👉 Vaporosity is a measure of the degree to which a substance's vapor pressure decreases with an increase in temperature. It is often used in the context of gases, but can also be applied to liquids and solids. In a liquid, the vapor pressure of a gas decreases as the temperature increases because the molecules of the gas are no longer able to escape into the surrounding air. In contrast, when you boil water, all of the water's molecules become vaporized, increasing the overall vapor pressure of
