One mole of an ideal gas expands adiabatically from $200 \mathrm{~K}$ to $250 \mathrm{~K}$. If the specific heat of the gas at constant volume is $0.8 \mathrm{~kJ} \mathrm{~kg}^{-1} \mathrm{~K}^{-1}$, then the work done by the gas is
  1. $20 \mathrm{~J}$
  2. $20 \mathrm{~kJ}$
  3. $40 \mathrm{~J}$
  4. $40 \mathrm{~kJ}$
