Question

why does cold air exert more pressure than warm air????​

Answer 1

Answer:

COLD AIR EXERTS MORE PRESSURE THAN WARM AIR BECAUSE WATER VAPOUR EFFECT: HUMID AIR IS LIGHTER (LESS DENSE) EXERTING LESS PRESSURE THAN DRY AIR AT THE SAME TEMPERATURE . THIS IS BECAUSE MOLECULAR WEIGHT OF WATER IS LESS THAN AVERAGE MOLECULAR WEIGHT OF DRY AIR . COLD, DRY IR PRODUCE HIGHER SURFACE PRESSURE THAN DO WARM , HUMID AIR.

Answer 2

Answer:

We have experienced that when we blow a balloon, the balloon becomes tight. If we try to fill more air, then the balloon will burst after an extent. This happens because air exerts pressure

We have also experienced the movement of fringes of windows and doors of our houses when wind blows in a high speed. This also happens because air exerts pressure
