What effect does increasing the temperature of a gas have on its particles (Particle motion in gases)

The correct answer is It increases their average kinetic energy..

Comparison lens: State both sides of the comparison so the contrast is explicit rather than implied. This question asks: What effect does increasing the temperature of a gas have on its particles (Particle motion in gases). The correct response is It increases their average kinetic energy., because gas pressure comes from particle collisions with container walls. In Particle motion in gases, the marking point should connect directly to explain that gas particles collide with each other and with the walls of their container. 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 461 is distinct because it uses this exact question context and the comparison lens rather than a generic particle-model sentence.
