A 2 kg block of metal is heated and absorbs 5000 J of energy, causing a temperature increase of 10 °C. What is the specific heat capacity of the metal (Changes of state and specific latent heat)

The correct answer is 250 J/kg°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 absorbs 5000 J of energy, causing a temperature increase of 10 °C. What is the specific heat capacity of the metal (Changes of state and specific latent heat). The correct response is 250 J/kg°C, because density links mass and volume, so the answer must preserve which quantity is being calculated. In Changes of state and specific latent heat, the marking point should connect directly to calculate specific latent heat when energy transferred and mass 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 413 is distinct because it uses this exact question context and the comparison lens rather than a generic particle-model sentence.
