If 5000 J of energy is required to raise the temperature of 1.5 kg of a substance by 10 °C, calculate the specific heat capacity of the substance (Temperature changes in a system and specific heat capacity)

333.33 J/kg°C

Application lens: Apply the rule to the specific sample or situation instead of reciting a broad fact. This question asks: If 5000 J of energy is required to raise the temperature of 1.5 kg of a substance by 10 °C, calculate the specific heat capacity of the substance (Temperature changes in a system and specific heat capacity). The correct response is 333.33 J/kg°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 319 is distinct because it uses this exact question context and the application lens rather than a generic particle-model sentence.
