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
