What happens to the temperature of a substance during a change of state (Temperature changes in a system and specific heat capacity)

The correct answer is The temperature remains constant.

Exam lens: Write the relationship, substitute values only when needed, and finish by interpreting the result. This question asks: What happens to the temperature of a substance during a change of state (Temperature changes in a system and specific heat capacity). The correct response is The temperature remains constant, 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 recall and apply the equation change in thermal energy = mass x specific heat capacity x temperature change. 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 287 is distinct because it uses this exact question context and the exam lens rather than a generic particle-model sentence.
