What is the definition of specific heat capacity?

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

Exam lens: Write the relationship, substitute values only when needed, and finish by interpreting the result. This question asks: What is the definition of specific heat capacity. 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 required practical activity 1: determine the specific heat capacity of one or more materials. 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 335 is distinct because it uses this exact question context and the exam lens rather than a generic particle-model sentence.
