    Starting with the same initial conditions, an ideal gas expands from volume V1V_{1} to V2V_{2} in three different ways. The work done by the gas is W1W_{1} if the process is purely isothermal. W2W_{2}. if the process is purely adiabatic and W3W_{3} if the process is purely isobaric. Then, choose the correct option
