How does increasing the temperature of a gas affect its pressure at constant volume (Particle motion in gases)

The correct answer is It increases the pressure.

Application lens: Apply the rule to the specific sample or situation instead of reciting a broad fact. This question asks: How does increasing the temperature of a gas affect its pressure at constant volume (Particle motion in gases). The correct response is It increases the pressure, because gas pressure comes from particle collisions with container walls. In Particle motion in gases, the marking point should connect directly to explain that the force from particle collisions produces gas 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 475 is distinct because it uses this exact question context and the application lens rather than a generic particle-model sentence.
