Question

Give two example of the fact that air exerts pressure

Answer 1

Two examples of the fact that air exerts pressure are:

1) When a balloon is filled with air, it swells up in size

2) Chips packets are blown with air at normal atmospheric pressure, but when we take them to mountains the packets swell up more, because the atmospheric pressure in mountainous region is less than the air pressure within the packet.

So, it is again a phenomenon which proves that air exerts pressure

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
