Question

A thermodynamic system goes in a cyclic process as represented in the above P-V diagram.
The network done during the complete cycle is given by the area:

• A. Cycle ACBDA
• B. $A{A}_2{B}_{2}BDA$
• C. $A{A}_2{B}_{2}B$
• D. Area not bounded by curve

Answer 1

The correct option is A Cycle ACBDA

As we know,

Work done, $W=$ Area under the curve.

And from the figure, it can be seen that net work done during the complete cycle is given by the closed area ACBDA.
