Question 252: Thermodynamics & KTG

Question

A thermodynamic system is taken from an original state D to an intermediate state E by the linear process shown in the figure. Its volume is then reduced to the original volume from E to F by an isobaric process. The total work done by the gas from D to E to F will be

Accepted Answer

Lets calculate area bounded by curve
$\mathrm{WDEF}=\mathrm{WDE}+\mathrm{WEF}+\mathrm{WFD}$.
$\begin{aligned} & =\frac{1}{2}(600+300) 	imes 3+(-300 	imes 3)+0 \\ \mathrm{WDEF} & =450 \mathrm{~J}\end{aligned}$
