Class 8 Physics Force and Pressure Pressure exerted by Liquids and Gases

Liquids also exert pressure in all directions on the walls of the container they are stored in. We see water coming out from leaking pipes and taps. In case of a bath shower and fountain, water comes out tiny holes.

Gases (Air) also exert pressure in all directions. When you make a hole on a fully inflated balloon, then does the balloon not break, thereby releasing all the air from inside.

Atmosphere (which means the air all around us) also exerts pressure. This is known as Atmospheric  Pressure. The value of atmospheric pressure is very high.
