1562 - Why does air's capacity to hold water vapor increase at a constant pressure when temperature rises?

Imagine air as a container that can hold water vapor. When the temperature of the air increases, the "container" gets bigger, meaning it can hold more water vapor.

This happens because warmer air molecules move faster and spread out. The space between these molecules increases, allowing more water vapor molecules to fit in. This is why warm air can hold more water vapor than cold air at the same pressure.
