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

Answer» As it is clear from the above figure, Change in pressure, dp = EF = 5.0 - 2.0 = 3.0 atm = 3.0 x 105 Nm-2 Change in volume, dV = DF = 600 -300 = 300 c.c = 300 x 10-6 m3 Work done by the gas from D to E to F = Area of ΔDEF w 1/2 = DF x EF = (300 X 10-6) x (3.0 x 105) = 45 J. |
