Total: 10
A thermodynamic system is taken from an original state to anintermediate state by the linear process shown in figure.
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.
Solution:
Total work done by gas equals to area enclosed.
W = Area DEFD
=
× E F × D F
=
× ( 5 − 2 ) × ( 600 − 300 )
= 450 J
W = Area DEFD
