Heat energy absorbed by a system in going through a cyclic process shown in the given figure is :

10\(^7 \pi\) J 10\(^4 \pi\) J 10\(^2 \pi\) J 10\(^{-3} \pi\) J

10\(^2 \pi\) J

As \(\Delta U = 0\) in a cyclic process \(\Delta Q = \Delta W = \text{ area of circle } = \pi r^2\) \(\Delta W = 10^2 \pi\) J
