A 2 kg block of metal is heated, causing a thermal energy change of 4000 J. If the specific heat capacity of the metal is 500 J/kg°C, what is the temperature change (Temperature changes in a system and specific heat capacity)

The correct answer is 8°C.

Practical lens: Link apparatus, readings, and uncertainty to the exact measurement named in the objective. This question asks: A 2 kg block of metal is heated, causing a thermal energy change of 4000 J. If the specific heat capacity of the metal is 500 J/kg°C, what is the temperature change (Temperature changes in a system and specific heat capacity). The correct response is 8°C, 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 mass when thermal energy change, 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 302 is distinct because it uses this exact question context and the practical lens rather than a generic particle-model sentence.
