A sample of $1$ mole gas at temperature $\mathrm{T}$ is adiabatically expanded to double its volume. If adiabatic constant for the gas is $\gamma=\frac{3}{2}$, then the work done by the gas in the process is:
  • A$\mathrm{RT}[2-\sqrt{2}]$
  • B$\frac{\mathrm{R}}{\mathrm{T}}[2-\sqrt{2}]$
  • C$\mathrm{RT}[2+\sqrt{2}]$
  • D$\frac{T}{R}[2+\sqrt{2}]$
