What effect does increasing the temperature of a gas have on the average kinetic energy of its particles (Pressure in gases (physics only))

The correct answer is It increases the 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 the average kinetic energy of its particles (Pressure in gases (physics only)). The correct response is It increases the average kinetic energy, 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) Apply the relationship pressure x volume = constant for a fixed mass of gas at constant temperature. 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 545 is distinct because it uses this exact question context and the comparison lens rather than a generic particle-model sentence.
