Question

Gas exerts the pressure on the walls of the container. Explain

Answer 1

because gases have more interparticle spaces between them so the gases moves away and hits the walls 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.
