Question

Suggest an activity which shows gases exert pressure on the wall of

container​

Answer 1

Explanation:

Procedure - Take a balloon and tie it at the lower end of a glass tube and hold vertically as in figure (a). Pour some water in the tube, balloon bulges out as in fig (b) because the water column exerts pressure at its bottom.

Observation - Force on the balloon is equal to the weight of the water column which is called Thrust. Also, pressure exerted by the water P = Thrust/Area of bottom of the tube.

This shows that a liquid exerts pressure at the bottom of the container in which it is kept.
