Warmer air can hold more water vapor than colder air, and the amount of water vapor the air can hold increases exponentially with temperature. Using the Clausius-Clapeyron equation, we can calculate that at 20°C, air can hold approximately 5 times more water vapor than air at 0°C. Therefore, saturated air at 20°C would have approximately 5 times more water vapor than saturated air at 0°C.
