Eli5: what makes cold air a moisture vacuum? I get that cold air doesn’t hold water like warm air, but I don’t get why?

Like what is the difference between cold and warm air besides the temperature, and why does the temperature matter?

It’s all about temperature. Hot = molecules moving faster. The faster water molecules move, the more they fly into the air. The slower they move, the more likely they are to fall and be liquid, and less likely to fly into the air in the first place.

This idea is called vapor pressure.
