How does increasing the temperature of a gas affect the average kinetic energy of its particles (Particle motion in gases)

The correct answer is It increases the average kinetic energy.

Boundary lens: Keep this separate from nearby specification points that use similar words but test a different idea. This question asks: How does increasing the temperature of a gas affect the average kinetic energy of its particles (Particle motion in gases). The correct response is It increases the 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 use the particle model to explain why gas pressure changes when gas particles collide with container walls. 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 502 is distinct because it uses this exact question context and the boundary lens rather than a generic particle-model sentence.
