148261 Certain amount of heat supplied to an ideal gas under isothermal condition will result in

Thermodynamics

148263 Five moles of an ideal gas has pressure $p_{0}$, volume $V_{0}$ and temperature $T_{0}$. The gas is expanded to volume $3 \mathrm{~V}_{0}$ along a path, so that the pressure $p$ is changed as function of volume $V$ as $p=p_{0}\left(V / V_{0}\right)$. The pressure is then reduced to $p_{0}$ maintaining the volume constant. The gas undergoes an isobaric compression till the volume and temperature become $V_{0}$ and $T_{0}$, respectively. The total work done by the gas during the entire process is

1 $\mathrm{p}_{0} \mathrm{~V}_{0} / 3$
2 $3 \mathrm{p}_{0} \mathrm{~V}_{0}$
3 $5 \mathrm{p}_{0} \mathrm{~V}_{0} / 3$
4 $2 \mathrm{p}_{0} \mathrm{~V}_{0}$
