What is the primary distinction between temperature and internal energy (Internal energy)

The correct answer is Temperature measures the average kinetic energy of particles, while internal energy is the total kinetic and potential energy..

Comparison lens: State both sides of the comparison so the contrast is explicit rather than implied. This question asks: What is the primary distinction between temperature and internal energy (Internal energy). The correct response is Temperature measures the average kinetic energy of particles, while internal energy is the total kinetic and potential energy., because internal energy combines particle kinetic and potential energy. In Internal energy, the marking point should connect directly to distinguish temperature from 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 245 is distinct because it uses this exact question context and the comparison lens rather than a generic particle-model sentence.
