Question
Inversion temperature is defined as the temperature above which a gas gets warm up and below which, the gas become cooler, when expanded adiabatically. Boyle temperature for a gas is $20^\circ\text{C}$. What will happen to the gas if it is adiabatically expanded at $50^\circ\text{C}$?
Answer: B
💡 Solution & Explanation
Inversion temperature $T_i = 2 T_B = 2 \times 293.15 = 586.3\text{ K}$. A starting temperature of $50^\circ\text{C}$ ($323.15\text{ K}$) resides cleanly below the inversion temperature, guaranteeing Joule-Thomson expansion induces cooling.
