A steadily flowing ideal gas undergoes adiabatic throttling where T1 is temperature before throttling and T2 is temperature after throttling. Assuming no change in kinetic and potential energy due to throttling, which of the following is correct?
1
T1 = T2
2
T2 = γT1, γ: specific heat ratio
3
T1 < T2
4
T1 = γT2, γ: specific heat ratio
