A 2 kg block of metal is heated, and it absorbs 8000 J of energy. If the specific heat capacity of the metal is 200 J/kg°C, calculate the temperature change of the metal (Temperature changes in a system and specific heat capacity)

20 °C

Comparison lens: State both sides of the comparison so the contrast is explicit rather than implied. This question asks: A 2 kg block of metal is heated, and it absorbs 8000 J of energy. If the specific heat capacity of the metal is 200 J/kg°C, calculate the temperature change of the metal (Temperature changes in a system and specific heat capacity). The correct response is 20 °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 temperature change when energy change, mass and specific heat capacity 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 317 is distinct because it uses this exact question context and the comparison lens rather than a generic particle-model sentence.
