Starting with the same initial conditions, an ideal gas expands from volume $\mathrm{V_{1}}$ to $\mathrm{V_{2}}$ in three different ways. The work done by the gas is $\mathrm{W_{1}}$ if the process is purely isothermal, $\mathrm{W_{2}}$ , if the process is purely adiabatic and $\mathrm{W_{3}}$ if the process is purely isobaric. Then, choose the correct option
Option: 1
$\mathrm{W_{1}<W_{2}<W_{3}}$

Option: 2
$\mathrm{W_{2}<W_{3}<W_{1}}$

Option: 3
$\mathrm{W_{3}<W_{1}<W_{2}}$

Option: 4
$\mathrm{W_{2}<W_{1}<W_{3}}$

$\text{area under P-V graph give work done.}$

So $\mathrm{W_{3}>W_{1}>W_{2}}$

Hence the correct option is 4
