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 purely isobaric and \[{{W}_{3}}\] if purely adiabatic. Then

A. \[{{W}_{2}}>{{W}_{1}}>{{W}_{3}}\]
B. \[{{W}_{2}}>{{W}_{3}}>{{W}_{1}}\]
C. \[{{W}_{1}}>{{W}_{2}}>{{W}_{3}}\]
D. \[{{W}_{1}}>{{W}_{3}}>{{W}_{2}}\]
Answer» B. \[{{W}_{2}}>{{W}_{3}}>{{W}_{1}}\]
