Which option best answers the regular-solid method checkpoint for Calculate thermal energy change when mass, specific heat capacity and temperature change are known. in Temperature changes in a system and specific heat capacity?

The correct answer is For a regular solid, dimensions give volume before density is calculated. (regular-solid method)..

Exam lens: Write the relationship, substitute values only when needed, and finish by interpreting the result. This question asks: Which option best answers the regular-solid method checkpoint for Calculate thermal energy change when mass, specific heat capacity and temperature change are known. in Temperature changes in a system and specific heat capacity. The correct response is For a regular solid, dimensions give volume before density is calculated. (regular-solid method)., 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 calculate thermal energy change when mass, specific heat capacity and temperature change are known. 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 299 is distinct because it uses this exact question context and the exam lens rather than a generic particle-model sentence.
