Question 571: Thermodynamics & KTG

Question

An ideal gas has undergone through the cyclic process as shown in the figure. Work done by the gas in the entire cycle is ________ $	imes 10^{-1} \mathrm{~J}$.
(Take $\pi=3.14$ )

Accepted Answer

$$\begin{aligned}
&	ext { Area of circle, } W=\frac{\pi}{4} d_1 d_2\
&\begin{aligned}
& \mathrm{W}=\frac{\pi}{4}(500-300) 	imes 10^3(350-150) 	imes 10^{-6} \
& \mathrm{~W}=31.4 \mathrm{Joule} \
& \mathrm{~W}=314 	imes 10^{-1} \mathrm{Joule}
\end{aligned}
\end{aligned}$$
