Short explanation

(Physics only) (HT only) Use the particle model to explain energy transfer during gas compression. Unit lens: Check the units before giving the final statement so the physics quantity is not swapped. In Increasing the pressure of a gas (physics only) (HT only), this means gas pressure comes from particle collisions with container walls. The answer should use the approved wording from Particle model and pressure, include compression, energy transfer, HT only, 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 90 is specific to (Physics only) (HT only) Use the particle model to explain energy transfer during gas compression and does not reuse a generic explanation from a neighbouring objective.

Misunderstanding Energy Transfer in Gas Compression: Emphasize that compressing a gas transfers energy to the gas, increasing its internal energy and temperature, and clarify the distinction between pressure and internal energy.
