What happens to the internal energy of a system when it is heated ? P43-057 Temperature changes in a system and specific heat capacity checkpoint

The correct answer is It increases ? P43-057 specific heat capacity reasoning.

Unit lens: Check the units before giving the final statement so the physics quantity is not swapped. This question asks: What happens to the internal energy of a system when it is heated ?. The correct response is It increases ? P43-057 specific heat capacity reasoning, 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 277 is distinct because it uses this exact question context and the unit lens rather than a generic particle-model sentence.
