State two experiences that made you think that air exerts pressure (other than those given in the text).
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 the air exerts pressure.
We have also experienced the movement of fringes of windows and doors of our houses when the wind blows at a high speed. This also happens because air exerts pressure.
