Isobaric process

Vedclass · Answer

(B) The work done by a gas during expansion is given by the area under the $PV$ curve with respect to the volume axis,i.e.,$W = \int_{V_1}^{V_2} P \, dV$.From the given $PV$ diagram,for the same change in volume from $V_1$ to $V_2$,the pressure $P$ remains highest for the isobaric process compared to the isothermal and adiabatic processes.Since the area under the curve is the greatest for the isobaric process,the work done is also the greatest for the isobaric process.

$A$ sample of gas expands from $V_1$ to $V_2$. In which of the following processes will the work done be greatest?
