What happens to the temperature of a gas when its internal energy increases (Increasing the pressure of a gas (physics only) (HT only))

The correct answer is The temperature increases..

Evidence lens: Use the data, graph feature, practical observation, or particle behaviour that proves the answer. This question asks: What happens to the temperature of a gas when its internal energy increases (Increasing the pressure of a gas (physics only) (HT only)). The correct response is The temperature increases., because gas pressure comes from particle collisions with container walls. In Increasing the pressure of a gas (physics only) (HT only), the marking point should connect directly to (Physics only) (HT only) Explain that increasing internal energy can increase the temperature of a gas. If the question includes values, the working must keep the appropriate unit and operation; if it is an explanation, it must name the relevant particle behaviour or energy change. This item belongs to Particle model and pressure, so avoid answers that switch to a different quantity, confuse heat with temperature, or describe gas pressure without collisions when collisions are the reason. Checkpoint 597 is distinct because it uses this exact question context and the evidence lens rather than a generic particle-model sentence.
