How does increasing the pressure of a gas affect the frequency of particle collisions with the container walls (Increasing the pressure of a gas (physics only) (HT only))

The correct answer is It increases the frequency.

Exam lens: Write the relationship, substitute values only when needed, and finish by interpreting the result. This question asks: How does increasing the pressure of a gas affect the frequency of particle collisions with the container walls (Increasing the pressure of a gas (physics only) (HT only)). The correct response is It increases the frequency, 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) Apply conservation of energy reasoning to work done on 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 635 is distinct because it uses this exact question context and the exam lens rather than a generic particle-model sentence.
