Question

  1. A. Higher pressure means fewer collisions.
  2. B. Higher pressure means more collisions.
  3. C. Pressure has no effect on collisions.
  4. D. Collisions only occur at low pressure.

Answer

The correct answer is Higher pressure means more collisions..

Explanation

Evidence lens: Use the data, graph feature, practical observation, or particle behaviour that proves the answer. This question asks: What is the relationship between gas pressure and the frequency of particle collisions with container walls (Particle motion in gases). The correct response is Higher pressure means more collisions., because gas pressure comes from particle collisions with container walls. In Particle motion in gases, the marking point should connect directly to describe how increasing temperature increases the average kinetic energy of gas particles. 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 477 is distinct because it uses this exact question context and the evidence lens rather than a generic particle-model sentence.

Common mistake

Temperature and Kinetic Energy Confusion

Students often confuse temperature with the average kinetic energy of gas particles, thinking they are the same concept.

Remember that temperature is a measure of the average kinetic energy of the particles in a substance. Increasing temperature means the particles move faster, which increases their average kinetic energy.
