In an adiabatic expansion of a gas, the initial and final temperatures are $T_1$ and $T_2$ respectively. Then, the change in internal energy of the gas is:
$[R = \text{gas constant}, \gamma = \text{adiabatic ratio}]$
$[R = \text{gas constant}, \gamma = \text{adiabatic ratio}]$
- Azero
- B$\frac{nR}{\gamma-1}(T_1-T_2)$
- C$\frac{nR}{\gamma-1}(T_2-T_1)$
- D$nR(T_1-T_2)$
