Question

Quizplus · Accepted Answer

The temperature of the air primarily controls how much water can be present as a gas. Warmer air can hold more water vapor than cooler air. This is because increasing the temperature leads to an increase in the saturation vapor pressure of water, which is the maximum amount of water vapor that can exist in the air at a given temperature. So, as the temperature increases, the air can hold more water vapor.
