Question

give two examples from everyday life which show that air exerts pressure ​

Answer 1

1. WHEN AIR IS PUMPED INSIDE A BALLOON,IT EXPANDS IN SIZE.THIS SHOWS THAT THE AIR INSIDE EXERTS PRESSURE ON THE WALL OF THE BALLOON

2.A SEALED PACKET OF CHIPS SWELLS UP IN THE MOUNTAIN . THIS IS BECAUSE ATMOSPHERIC PRESSURE AT HIGHER ALTITUDES IS LESS WHEREAS THE PACKET IS FILLED WITH GAS AT NORMAL ATMOSPHERIC PRESSURE . IT THEREFORE SWELLS UP IN THE MOUNTAINS,AS THE PRESSURE INSIDE IS MORE THAN THE ATMOSPHERIC PRESSURE
