Use the particle model to explain why gas pressure changes when gas particles collide with container walls.

Use the particle model to explain why gas pressure changes when gas particles collide with container walls. Application lens: Apply the rule to the specific sample or situation instead of reciting a broad fact. 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 pressure, gas particles, container, wall, 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 72 is specific to use the particle model to explain why gas pressure changes when gas particles collide with container walls and does not reuse a generic explanation from a neighbouring objective.
