Question

Give reason why gases exert pressure on the walls of container. Gases undergo diffusion very fast

Answer 1

According to KINETIC THEORY OFGASES , The pressure of the gas is due to continous collision of molecules on the wall of container because the gasmolecule always move in random motion. Its not limited to gaseverything which has mass exert pressure. But the unique property ofgases is that THEY FILL THE SP

Answer 2

Explanation:

Gases have high KE due to which particles keeps on moving rapidly as a result particles hits the walls of the container and exert pressure.

they undergoes fast as there particles are very far away from each others
