How does the arrangement of particles affect their potential energy?

The correct answer is Further apart particles have higher potential energy..

Unit lens: Check the units before giving the final statement so the physics quantity is not swapped. This question asks: How does the arrangement of particles affect their potential energy. The correct response is Further apart particles have higher potential energy., because density links mass and volume, so the answer must preserve which quantity is being calculated. In Temperature changes in a system and specific heat capacity, the marking point should connect directly to identify change in thermal energy in joules, mass in kilograms, specific heat capacity in joules per kilogram per degree Celsius and temperature change in degrees Celsius. 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 289 is distinct because it uses this exact question context and the unit lens rather than a generic particle-model sentence.
