Q. 63 Two moles of a monoatomic ideal gas at 10 atm and $300 \mathrm{~K}$ is expanded isothermally and reversibly to a pressure of $2 \mathrm{~atm}$. The absolute value of work done by the system is (in $\mathrm{kJ}$ ) (rounded off to two decimal places) Given: $\mathrm{R}=8.31 \mathrm{~J} \mathrm{~mol}^{-1} \mathrm{~K}^{-1}, 1 \mathrm{~atm}=101 \mathrm{kPa}$
