• # question_answer If the inversion temperature of a gas is $-{{80}^{o}}C$, then it will produce cooling under Joule-Thomson effect at A)                 298 K     B)                 273 K C)                 193 K     D)                 173 K

If inversion temperature is ${{80}^{o}}C={{193}^{o}}K$ then the temperature, at which it will produce cooling under Joule Thomson?s effect, would be below inversion temperature except ${{173}^{o}}K$all other values given as
