What principle describes the maximum amount of moisture air can hold at a given temperature?

The saturation point is the principle that defines the maximum amount of moisture that air can hold at a specific temperature. As air temperature increases, its capacity to hold water vapor also increases, meaning warmer air can hold more moisture before it becomes saturated. When the air reaches this saturation point, it is said to be fully saturated with water vapor, and additional moisture can lead to condensation, resulting in phenomena such as dew, fog, or precipitation.

In terms of understanding humidity, the saturation point is crucial because it influences weather patterns and climate conditions. For instance, when the humidity reaches 100%, the air is at its saturation point, and this condition is vital for the development of clouds and rain. Recognizing this relationship between temperature and moisture capacity allows us to understand various atmospheric processes better.
