Question

(a)

Explain, in terms of the momentum of molecules, how the gas in the balloon exerts
a pressure.​

Answer 1

Explanation: 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.
