Using

Cyclic Process -

A cyclic process consist of a number of changes that return the system back to its initial state.

 

- wherein

in cyclic process Delta U= 0

 

 Work done in cyclic process = Area of the cycle

In the upper half, cycle is anti-clockwise while in lower half it is clockwise. Hence, net work done is zero.


Option 1)

P_{o}V_{o}

This option is incorrect

Option 2)

2P_{o}V_{o}

This option is incorrect

Option 3)

\frac{P_{o}V_{o}}{2}

This option is incorrect

Option 4)
