A sealed chamber in a particle detector contains a gas. The gas exerts pressure on a thin window of the chamber.
Which process produces the force on the window when a gas particle reaches it?
The particle is repelled before touching the window and transfers force across the gap.
The particle slides along the window and produces a force only parallel to it.
The particle rebounds and exerts an equal and opposite force on the window.
The particle remains against the window and pushes on it continuously.
