What is the effect of increasing the internal energy of a gas on its particle motion (Increasing the pressure of a gas (physics only) (HT only))

The correct answer is Particles move faster..

Exam lens: Write the relationship, substitute values only when needed, and finish by interpreting the result. This question asks: What is the effect of increasing the internal energy of a gas on its particle motion (Increasing the pressure of a gas (physics only) (HT only)). The correct response is Particles move faster., 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 that increasing internal energy can increase the temperature of a gas. 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 599 is distinct because it uses this exact question context and the exam lens rather than a generic particle-model sentence.
