For a constant volume process _____________ by the system is used only to increase the internal energy?
Correct answer: C. Heat absorbed
- A. Both A. & B
- B. Work done
- C. Heat absorbed
- D. Neither A. nor B
Explanation
For a constant-volume process, boundary work is W = ∫P dV = 0 because the volume does not change. Therefore, heat absorbed by the system increases its internal energy according to the first law.
