What is the specific heat capacity of a substance?

The specific heat capacity of a substance is defined as the amount of energy required to raise the temperature of one kilogram of the substance by one degree Celsius.

Practical lens: Link apparatus, readings, and uncertainty to the exact measurement named in the objective. This question asks: What is the specific heat capacity of a substance. The correct response is The specific heat capacity of a substance is defined as the amount of energy required to raise the temperature of one kilogram of the 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 describe why insulation is used in specific heat capacity experiments. 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 338 is distinct because it uses this exact question context and the practical lens rather than a generic particle-model sentence.
