Question

Why does cold air exert more pressure than warm air ?
Give reason .​

Answer 1

Explanation:

Greater activity of the heated molecules increases the spacing between neighboring molecules and thus reduces air density. The decreasing air density then lowers the pressure exerted by the air. Warm air is thus lighter (less dense) than cold air and consequently exerts less pressure.

Answer 2

Answer:

Cold air exerts more pressure than warm air as cold air is denser than warm air while warm air is lighter and less denser than warm air so less pressure is exerted.
