Question

why do gas exert pressure​

Answer 1

The molecules are continually colliding with each other and with the walls of the container. When a molecule collides with the wall, they exert small force on the wall The pressure exerted by the gas is due to the sum of all these collision forces.The more particles that hit the walls, the higher the pressure

Answer 2

exerts pressure because the molecule is very far from them and there is no intermolecular space between them. gases have more kinetic energy and they both the walls of the container in which they are filled so gases exerts pressure.
