A gas having a negative Joule-Thomson effect (mu < 0) when throttled will
- A. Become cooler
- B. Become warmer
- C. Remain at the same temperature
- D. Either be cooler or warmer depending on the type of gas
Answer: B. Become warmer
Explanation: The Joule-Thomson coefficient (mu) indicates the change in temperature with respect to pressure during throttling. In the heating region, mu is negative, meaning that a drop in pressure results in an increase in temperature, thus making the gas warmer.
