With rise in temperature, the heat capacity of a substance___________________?
Correct answer: A. Increases
- A. Increases
- B. Decreases
- C. Remains unchanged
- D. Either A. or B.; depends on the substance
Explanation
Over ordinary temperature ranges, the heat capacity of most substances increases because more molecular energy modes become accessible as temperature rises. This is the standard engineering approximation, although unusual materials or phase changes can show exceptions.
