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, leading to more energetic collisions.

Graph lens: Read the trend, flat section, gradient, or axis labels before explaining the physical meaning. 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, leading to more energetic collisions., 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 why a gas may get hotter when it is compressed quickly. 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 603 is distinct because it uses this exact question context and the graph lens rather than a generic particle-model sentence.
