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