- Five moles of an ideal gas has pressure \(p_0\) volume \(V_0\) and temperature \(T_0\). The gas is expanded to volume \(3 V_0\) 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.
