What is the relationship between temperature and internal energy?

The correct answer is Temperature is a measure of average kinetic energy, while internal energy includes potential energy.

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 internal energy. The correct response is Temperature is a measure of average kinetic energy, while internal energy includes potential energy, because internal energy combines particle kinetic and potential energy. In Internal energy, the marking point should connect directly to use particle motion and particle arrangement to describe changes in internal energy. 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 265 is distinct because it uses this exact question context and the unit lens rather than a generic particle-model sentence.
