Starting with 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 purely isobaric and `W_3` if purely adiabatic. Then

A

`W_2gtW_3gtW_1`

B

`W_1gtW_2gtW_3`

C

`W_1 gt W_3gt W_2`

D

`W_2gtW_1gtW_3`
