A thermodynamic system is taken through cyclic process. The total work done in the process is :
A thermodynamic system is taken through cyclic process. The total work done in the process is :

Options

  1. A100 J100 \mathrm{~J}
  2. B300 J300 \mathrm{~J}
  3. CZero
  4. D200 J200 \mathrm{~J}

Correct answer

B. 300 J300 \mathrm{~J}

Step-by-step solution

Work done = Area under the curve
⇒W=12×(4−2)×(400−100)=12(2)×300\Rightarrow \mathrm{W}=\frac{1}{2} \times(4-2) \times(400-100)=\frac{1}{2}(2) \times 300
W=300 J\mathrm{W}=300 \mathrm{~J}
