In the inversion curve for a gas, in the region of cooling:
Show Hint
- Joule-Kelvin coefficient is negative
- Joule-Kelvin coefficient is positive
- Joule-Kelvin coefficient is zero
- None of the three
The Correct Option is B
Solution and Explanation
\[ \mu_J = \left( \frac{\partial T}{\partial P} \right)_H \] - Cooling occurs when \( \mu_J>0 \) (i.e., temperature decreases as pressure decreases).
- Heating occurs when \( \mu_J<0 \) (temperature increases as pressure decreases).
- At the inversion temperature, \( \mu_J = 0 \).

An amount of ice of mass \( 10^{-3} \) kg and temperature \( -10^\circ C \) is transformed to vapor of temperature \( 110^\circ C \) by applying heat. The total amount of work required for this conversion is,
(Take, specific heat of ice = 2100 J kg\(^{-1}\) K\(^{-1}\),
specific heat of water = 4180 J kg\(^{-1}\) K\(^{-1}\),
specific heat of steam = 1920 J kg\(^{-1}\) K\(^{-1}\),
Latent heat of ice = \( 3.35 \times 10^5 \) J kg\(^{-1}\),
Latent heat of steam = \( 2.25 \times 10^6 \) J kg\(^{-1}\))- JEE Main - 2025
