Question

  1. A. Higher temperature means lower average kinetic energy.
  2. B. Higher temperature means higher average kinetic energy.
  3. C. Temperature does not affect average kinetic energy.
  4. D. Average kinetic energy is independent of temperature.

Answer

The correct answer is Higher temperature means higher average kinetic energy..

Explanation

Unit lens: Check the units before giving the final statement so the physics quantity is not swapped. This question asks: What is the relationship between temperature and the average kinetic energy of particles (Internal energy). The correct response is Higher temperature means higher average kinetic energy., because internal energy combines particle kinetic and potential energy. In Internal energy, the marking point should connect directly to describe how increasing temperature increases the average kinetic energy of 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 Internal energy and energy transfers, 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 229 is distinct because it uses this exact question context and the unit lens rather than a generic particle-model sentence.

Common mistake

Confusing Temperature and Kinetic Energy

Students often confuse temperature with the average kinetic energy of particles, thinking that a higher temperature means a higher total kinetic energy of all particles in a system.

Emphasize that temperature is a measure of the average kinetic energy of particles, while total kinetic energy depends on both the number of particles and their individual kinetic energies.
