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

Answer: Option A

Solution(By Examveda Team)

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.
