Question

1. Explain in terms of particle collisions and Dalton’s law why it can be assumed that the total pressure inside the gas collection tube is equal to the atmospheric pressure outside of the tube.

Answer 1

The particles inside the container are exerting force on the walls of the container, while the particles outside of the container are also exerting force. If there were any less pressure from the inside, the tube would collapse. If there were any less pressure from the outside, the tube would explode. Hope it helps in any way.
