  4. D. The temperature fluctuates

Answer

The correct answer is The temperature increases.

Explanation

Particle lens: Describe arrangement, motion, spacing, collisions, or energy changes only when they are relevant here. This question asks: In a specific heat capacity experiment, what happens to the temperature of a substance when energy is transferred to it (Temperature changes in a system and specific heat capacity). The correct response is The temperature increases, because specific heat capacity links energy, mass, material and temperature change. In Temperature changes in a system and specific heat capacity, the marking point should connect directly to interpret temperature-time data from a specific heat capacity experiment. 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 348 is distinct because it uses this exact question context and the particle lens rather than a generic particle-model sentence.

Common mistake

Confusing temperature change with internal energy change

Students often think the temperature rise shown in a temperature‑time graph directly represents the total internal energy change of the system, ignoring that the graph only shows the average kinetic energy of the particles, not the potential energy component or the total internal energy.

Explain that the temperature‑time graph records only the change in average kinetic energy of the particles. The total internal energy change also includes any change in potential energy of the particles, which is not shown on the graph. Clarify that the graph is a visual representation of kinetic energy change, not the complete internal energy change.
