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

Options

A. `W_(2) gt W_(1) gt W_(3)`
B. `W_(2) gt W_(3) gt W_(1)`
C. `W_(1) gt W_(2) gt W_(3)`
D. `W_(1) gt W_(3) gt W_(2)`

Answer

A

Explanation

As W.D. in isobaric `gt W.D.` in Isothermal `gt` W.D. in adiabatic
`or W_(2) gt W_(1) gt W_(3)`
