Chemical Engineering Thermodynamics

During Joule-Thomson expansion of gases

  • A. Enthalpy remains constant
  • B. Entropy remains constant
  • C. Temperature remains constant
  • D. None of these
Answer: Option A.

During, joule-thomson effect basically the change in internal (inter-molecular) energy and change in pressure energy will be equal to zero hence, enthalpy will remain constant.
or H=constant.
