Heat capacity is proportional to how much substance is present, which makes it:
AA chemical property
BA colligative property
CAn extensive property
DAn intensive property
Answer & Solution
Correct answer: C. An extensive property
1. Doubling the amount of a substance doubles the energy needed to warm it by one degree.
2. Heat capacity is therefore an extensive property, its value being proportional to the amount of the substance.
3. Specific heat, by contrast, is an intensive property.
4. For specific heat the type, but not the amount, of the substance is all that matters.
