What does specific heat capacity measure?

The correct answer is The energy needed to raise the temperature of one kilogram of a substance by one degree Celsius.

Evidence lens: Use the data, graph feature, practical observation, or particle behaviour that proves the answer. This question asks: What does specific heat capacity measure. The correct response is The energy needed to raise the temperature of one kilogram of a substance by one degree Celsius, 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 interpret temperature-time data from a specific heat capacity experiment. 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 345 is distinct because it uses this exact question context and the evidence lens rather than a generic particle-model sentence.
