## The amount of heat needed to raise the temperature of 10kg of copper by 1K is its ____

A. specific heat capacity

B. latent heat

C. heat capacity

D. internal energy

C

## EXPLANATION…

Please note the difference between heat capacity and specific heat capacity.

While heat capacity is the amount of heat energy required to change the temperature of any amount of a substance by 1 kelvin, specific heat capacity on the other hand is the amount of heat energy required to change the temperature of 1 kilogram of a substance by 1 kelvin.

In this question, 10kg and not 1kg of copper is involved, so, the heat capacity is not specific.

### Now for the right answer to the above question:

1. Option A is incorrect. 1kg of copper would have made the heat capacity specific.
2. Option B is incorrect. latent heat involves the heat required to change state.
3. C is correct. heat capacity is the right answer.
4. D is not the correct answer. The concept of internal energy is not within the scope of the subject matter.
