Question

A real gas within a closed chamber at \( 27^{\circ} C \) undergoes the cyclic process as shown in figure. The gas obeys \( PV ^{3}= \) RT equation for the path \( A \) to \( B \). The net work done in the complete cycle is (assuming \( R =8 J / molK \) ):

solve by work done in polytropic process formula for path Ato B 

Answer 1

 For A to B :

Given \(PV^3 =RT\Rightarrow P = \frac{RT}{V^3}\) 

\(W_{nct} = W_{AB} + W_{BC} + W_{CA} = 225 - 20 + 0 = 205\ J\)
