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

A $200J$
B $300J$
C $100J$
DZero

Correct answer

B. $300J$

Step-by-step solution

The work done is given by the area of the $PV$ graph of the loop.
$W = \dfrac{1}{2}\left({V}_{E} - {V}_{C}\right) ( {P}_{D} - {P}_{C} ) = \dfrac{2 \times 300}{2}J$
$= 300J$
