A thermodynamic system is taken from an original state D to an intermediate state E by the linear process shown in Fig. 8(NCT).1. Its volume is then reduced to the original value from E to D via F by an isobaric process. Calculate the total work done by the gas from D to £ to F to D.  

Answer:

As is clear from Fig. 8(NCT).1,                                     Change in pressure, Change in volume, dV =EF= 600 - 300 = 300 cc Work done by the. gas from D to E to F= area of
