1.	A thermodynamic system is taken from an original state to an intermediate state by the linear process shown in Fig.Its volume is then reduced to the original value from E to F by an isobaric process. Calculate the total work done by the gas from D to E to F.
Answer» SOLUTION :TOTAL WORK done by the gas from D to E to F. `W=W_(DE)+W_(EF)` = Area of trapezium DEGHD – Area of rectangle EFHG = Area of triangle DEF `=1/2DE xx FE` `=1/2(600-300) Nm^(-2) xx(5.0-2.0)m^3` = 450 J.
