During Joule-Thomson expansion of gases_________________?
Correct answer: A. Enthalpy remains constant
- A. Enthalpy remains constant
- B. Entropy remains constant
- C. Temperature remains constant
- D. None of these
Explanation
Throttling is a steady-flow process with negligible heat and work transfer, making it isenthalpic, so enthalpy remains constant. Entropy generally increases and temperature need not remain constant.
