Question

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

• A. ${10}^7\pi \text{J}$
• B. ${10}^4\pi \text{J}$
• C. ${10}^2\pi \text{J}$
• D. ${10}^{-3}\pi \text{J}$

Answer 1

The correct option is C ${10}^2\pi \text{J}$

In a cyclic process, $\Delta U=0$
We know that the work done is given by the area enclosed.
So, $\Delta W=\pi (10{)}^2$
