All gases above its inversion temperature, in a throttling process will show

A A heating effect
B No change in temperature
C A cooling effect
D Either A or C

Correct Answer: A heating effect

Above the inversion temperature joul thomson coefficient $$\left( \mu \right) = {\left( {\frac{{\partial T}}{{\partial P}}} \right)_H}{\text{ is }} - {\text{ve}}$$
So, on decreasing the pressure (throttling) the temperature increases.
