At higher temperatures, molal heat capacities for most of the gases (at constant pressure) _______________ with increase in temperature?
Correct answer: B. Increases
- A. Varies linearly
- B. Increases
- C. Decreases
- D. Does not vary
Explanation
For most gases, molecular rotational and vibrational contributions become more significant as temperature rises, so the molal heat capacity at constant pressure generally increases.
