Vedclass · Answer

(B) The work done in a cyclic process is equal to the area enclosed by the cycle in the $P-V$ diagram.The area is a rectangle with width $\Delta V = (300 - 100) 	ext{ cc} = 200 	imes 10^{-6} 	ext{ m}^3$ and height $\Delta P = (200 - 100) 	ext{ kPa} = 100 	imes 10^3 	ext{ Pa}$.Area $= \Delta P 	imes \Delta V = (100 	imes 10^3 	ext{ Pa}) 	imes (200 	imes 10^{-6} 	ext{ m}^3) = 20 	ext{ J}$.Since the cycle $PQRSP$ is traversed in an anticlockwise direction,the work done by the system is negative.Therefore,the work done is $W = -20 	ext{ J}$.

The work done in the cyclic process $PQRSP$ shown in the figure is .......... $J$.
