Question

Which of the following statement is incorrect?

• A. Joule-Thomson coefficient is zero at inversion temperature of a real gas
• B. Ideal gas do not show Joule-Thomson effect
• C. Inversion temperature of $H_2$ and He is very-very low
• D. Joule-Thomson coefficient $\mu ={\left(\frac{\delta P}{\delta T}\right)}_H$

Answer 1

Answer: (D)

Joule-Thomson coefficient $\mu ={\left(\frac{\delta P}{\delta T}\right)}_H;\mu =0$ at inversion temperature. Also ideal gas does not show Joule-Thomson effect. $H_2$ and $He$ have low value of $Ti$ and thus show heating effect if subjected for Joule Thomson effect
