Question
- A. Temperature is a measure of average kinetic energy, while internal energy is the total energy of all particles.
- B. Temperature measures total energy, while internal energy measures average energy.
- C. Temperature is always higher than internal energy.
- D. Internal energy is measured in degrees, while temperature is measured in joules.
Answer
The correct answer is Temperature is a measure of average kinetic energy, while internal energy is the total energy of all particles..
Explanation
Evidence lens: Use the data, graph feature, practical observation, or particle behaviour that proves the answer. This question asks: Which statement distinguishes temperature from internal energy. The correct response is Temperature is a measure of average kinetic energy, while internal energy is the total energy of all particles., because internal energy combines particle kinetic and potential energy. In Internal energy, the marking point should connect directly to describe how changing particle arrangement can change the potential 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 237 is distinct because it uses this exact question context and the evidence lens rather than a generic particle-model sentence.
Common mistake
Confusing Particle Arrangement with Temperature
Students often think that changing the arrangement of particles directly changes the temperature of a substance.
Emphasize that changing particle arrangement affects potential energy, while temperature is related to the average kinetic energy of particles.
