Question detail
A substance with a mass of 3 kg absorbs 1500 J of energy. If its specific heat capacity is 500 J/kg°C, what is the temperature change (Temperature changes in a system and specific heat capacity) (Temperature changes in a system and specific heat capacity; particle reasoning focus: Calculate temperature change when energy change, mass and specific heat capacity are known) (Temperature changes in a system and specific heat capacity; particle reasoning focus: Calculate temperature change when energy change, mass and specific heat capacity are known)

Question
- A. 1°C
- B. This confuses specific heat capacity with a different particle-model idea in Internal energy and energy transfers.
- C. This gives a vague particle statement without answering the particle reasoning focus.
- D. This reverses the cause and effect for Temperature changes in a system and specific heat capacity.
Answer
The correct answer is 1°C.
Explanation
Evidence lens: Use the data, graph feature, practical observation, or particle behaviour that proves the answer. This question asks: A substance with a mass of 3 kg absorbs 1500 J of energy. If its specific heat capacity is 500 J/kg°C, what is the temperature change (Temperature changes in a system and specific heat capacity) (Temperature changes in a system and specific heat capacity; particle reasoning focus: Calculate temperature change when energy change, mass and specific heat capacity are known) (Temperature changes in a system and specific heat capacity; particle reasoning focus: Calculate temperature change when energy change, mass and specific heat capacity are known). The correct response is 1°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 321 is distinct because it uses this exact question context and the evidence lens rather than a generic particle-model sentence.
Common mistake
Confusing Temperature Change with Energy Change
Students often think that a change in temperature directly indicates a change in energy without considering mass and specific heat capacity.
Emphasize the relationship defined by the equation for thermal energy change, which includes mass and specific heat capacity, to clarify how energy change relates to temperature change.
