Question

liquid exerts pressure on the wall of the container by activity ​

Answer 1

Answer:

All the liquids exert pressure on the base or bottom and wall of their container.

All the liquids have weight, when we pour liquid into a vessel, then the weight of liquid pushes down on the base of the vessel producing a pressure.

Answer 2

Because in the gaseous state, the particles move about randomly at high speed. Due to this random movement, the particles hit each other and also the walls of the container. The pressure exerted by the gas is because of this force exerted by gas particles per unit area on the walls of the container.
