Question

A gas can exert pressure on the wall of container ?give
reason

Answer 1

Answer:

The air cannot be stopped and so it can also exert pressure on the wall of the container.

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.
