Question

A gas undergoing expansion through a porous plug exhibits cooling it is temperature is
(1)more than Boyle temperature
(2) less than critical temperature
(3) less than inversion temperature
(4) more than inversion temperature

Answer 1

Answer:

Option C

Explanation:

Among the four options given, the correct selection is;

A gas that undergoes expansion and its temperature will reduce if it is less than the inversion temperature

The inversion temperature is that critical temperature below which a non-ideal gas undergoing expansion will get through a temperature decrease, and above which will go through a temperature increase.

This phenomena was explained by Joule Thomson

Answer 2

A gas undergoing expansion through a porous plug exhibits come cooling it is temperature is less than inversion temperature due to the following reason:

- In thermodynamics, The critical temperature below which unknown non ideal gas undergoing expansion the temperature decreases is called the inversion temperature.

- Joule Thomas explained the phenomena.

- The inversion temperature if goes above then the temperature increases of the non ideal gas undergoing expansion. So, the temperature is less than inversion temperature due to cooling effect.

- So, The correct option is (C).
