In an adiabatic expansion, the temperature of one mole of an ideal monatomic gas $\displaystyle (\gamma=5 / 3)$ decreases from $\displaystyle 60$ K to $\displaystyle 50$ K . The work done by the gas in the process is : (Take the universal gas constant as $\displaystyle \mathrm{R}=8.3 \mathrm{~J} \mathrm{~mol}^{-1} \mathrm{~K}^{-1}$ )
