Throttling (Joule-Thomson effect) process is a constant __________ process.

Answer & Solution
Correct Answer: Option A
Joule – thomson throttling process is an iso-enthalpic process since pressure change is done at constant enthalpy that means a pressure change will occur but a corresponding internal energy change also occurs and enthalpy remains constant.
Since $$H = U + PV$$
