In Joule-Thomson porous plug experiment, the__________________?
Correct answer: C. None of these
- A. Enthalpy does not remain constant
- B. Entire apparatus is exposed to surroundings
- C. None of these
- D. Temperature remains constant
Explanation
A porous-plug experiment is a throttling process, and for steady flow with negligible heat transfer, work, and kinetic-energy changes, enthalpy remains constant. Temperature need not remain constant because the Joule-Thomson effect may cause heating or cooling.
