What is the effect of increasing the temperature of a gas on its average kinetic energy ? P43-069 Particle motion in gases checkpoint

The correct answer is The average kinetic energy increases ? P43-069 density measurement and calculation.

Cause lens: Name the cause, then state the effect on particles, pressure, density, or energy. This question asks: What is the effect of increasing the temperature of a gas on its average kinetic energy ?. The correct response is The average kinetic energy increases ? P43-069 density measurement and calculation, because density links mass and volume, so the answer must preserve which quantity is being calculated. In Particle motion in gases, the marking point should connect directly to use the particle model to explain why gas pressure increases when temperature increases at constant volume. 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 496 is distinct because it uses this exact question context and the cause lens rather than a generic particle-model sentence.
