What is the specific heat capacity of a substance, and how is it measured?

Specific heat capacity is defined as the amount of energy required to raise the temperature of one kilogram of a substance by one degree Celsius. It is measured by conducting experiments where the energy transferred to the substance is recorded along with the corresponding temperature change.

Boundary lens: Keep this separate from nearby specification points that use similar words but test a different idea. This question asks: What is the specific heat capacity of a substance, and how is it measured. The correct response is Specific heat capacity is defined as the amount of energy required to raise the temperature of one kilogram of a substance by one degree Celsius. It is measured by conducting experiments where the energy transferred to the substance is recorded along with the corresponding temperature change., 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 apply AT 1 and AT 5 skills when measuring temperature, mass and energy transfer. 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 358 is distinct because it uses this exact question context and the boundary lens rather than a generic particle-model sentence.
