I would like to know why hot air holds more water vapor. There is this question:
But I would like a more quantitative explanation. Ideally, an explanation based on, e.g., the perfect gas law, plus of course the intuitive reasoning behind the math. Should I ask a new question or should I put a bounty?
I don't have much reputation, but I could sacrifice it, if necessary. The only issue is that my requirements are quite different from those of the original question which doesn't mention any math. What should I do?
