Explain that faster gas particles collide more often and with greater force.

Explain that faster gas particles collide more often and with greater force. Comparison lens: State both sides of the comparison so the contrast is explicit rather than implied. In Particle motion in gases, this means gas pressure comes from particle collisions with container walls. The answer should use the approved wording from Particle model and pressure, include gas particles, force, and avoid drifting into another section of Particle model of matter. For revision, practise saying the exact objective aloud, then add the one calculation, particle movement, collision, graph, or practical detail that makes the statement true. A strong exam response for checkpoint 70 is specific to explain that faster gas particles collide more often and with greater force and does not reuse a generic explanation from a neighbouring objective.
