Which of the following units is used to measure specific heat capacity?

The correct answer is J/kg°C.

Boundary lens: Keep this separate from nearby specification points that use similar words but test a different idea. This question asks: Which of the following units is used to measure specific heat capacity. The correct response is J/kg°C, because specific heat capacity links energy, mass, material and temperature change. In Temperature changes in a system and specific heat capacity, the marking point should connect directly to define specific heat capacity as the energy needed to raise the temperature of one kilogram of a substance by one degree Celsius. 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 274 is distinct because it uses this exact question context and the boundary lens rather than a generic particle-model sentence.
