Starting with the same initial conditions, an ideal gas expands from volume $V_1$ to $V_2$ in three different ways. The work done by the gas is $W_1$ if the process is purely isothermal, $W_2$, if the process is purely adiabatic and $W_3$ if the process is purely isobaric. Then, choose the correct option

• Correct answer
  A

  $W_2<W_1<W_3$
• B

  $W_1<W_2<W_3$
• C

  $W_2<W_3<W_1$
• D

  $W_3<W_1<W_2$

Hence, the correct answer is option: 'A'.
