How does gas exert pressure? Explain using the change in momentum.

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.

(Here goes another answer) Gas pressure will be caused by the impact of the gas particles as they come into collison and strive a force on the container walls and once the degrees of the gas enlarge, the particles will then create kinetic energy and speed increases.

Hope this helps :)
