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