Describe how increasing temperature affects the average kinetic energy of gas particles.

Increasing the temperature of a gas increases the average kinetic energy of its particles. As temperature rises, the particles move faster, resulting in more energetic collisions with each other and the walls of the container.

Evidence lens: Use the data, graph feature, practical observation, or particle behaviour that proves the answer. This question asks: Describe how increasing temperature affects the average kinetic energy of gas particles. The correct response is Increasing the temperature of a gas increases the average kinetic energy of its particles. As temperature rises, the particles move faster, resulting in more energetic collisions with each other and the walls of the container., because density links mass and volume, so the answer must preserve which quantity is being calculated. In Pressure in gases (physics only), the marking point should connect directly to (Physics only) Explain why decreasing the volume of a gas at constant temperature increases its pressure. 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 525 is distinct because it uses this exact question context and the evidence lens rather than a generic particle-model sentence.
