  1. When an ideal gas with constant specific heats is throttled adiabatically, with negligible changes in kinetic and potential energies.
    1. ∆h = 0, ∆T = 0
    2. ∆h > 0, ∆T= 0
    3. ∆h > 0, ∆S > 0
    4. ∆h = 0, ∆S > 0
Correct Option: A

∆ h = 0, ∆ T = 0
Throttling is known as is isenthalpic process and as for ideal gas
H = f(T)
∆T = 0 also.
