The principle applied in liquefaction of gases is
A
Adiabatic expansion
B
Joule-Thomson effect
C
Both A and B
D
Neither A nor B
Correct Answer: Both A and B
The liquefication involves both adiabatic expansion and joule-thomson effect of change in pressure as we do the observations at adiabatic conditions during the flow of gas through orifice (joule Thomson effect).
