Question

  1. A. Higher internal energy always means lower temperature.
  2. B. Internal energy and temperature are unrelated.
  3. C. Higher internal energy generally leads to higher temperature.
  4. D. Temperature can increase without a change in internal energy.

Answer

The correct answer is Higher internal energy generally leads to higher temperature..

Explanation

Unit lens: Check the units before giving the final statement so the physics quantity is not swapped. This question asks: Which of the following best describes the relationship between internal energy and temperature in a gas (Increasing the pressure of a gas (physics only) (HT only)). The correct response is Higher internal energy generally leads to higher temperature., because gas pressure comes from particle collisions with container walls. In Increasing the pressure of a gas (physics only) (HT only), the marking point should connect directly to (Physics only) (HT only) Explain that increasing internal energy can increase the temperature of a gas. 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 601 is distinct because it uses this exact question context and the unit lens rather than a generic particle-model sentence.

Common mistake

Confusing Internal Energy and Temperature

Students often confuse internal energy with temperature, thinking that increasing internal energy directly means an increase in temperature without considering the context.

Clarify that while increasing internal energy can lead to an increase in temperature, it also depends on the mass and specific heat capacity of the gas. Emphasize the relationship between internal energy and temperature in the context of gas behavior.
