As we have learned

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

 

 In case of cyclic process 

U_f = U_i \Rightarrow \Delta U = 0 \\\\ \Delta U \propto \Delta T \: \: so \: \: \Delta T = 0

From FLOT \Delta Q = \Delta V + \Delta W \\\\ \Delta Q = \Delta W \\\\

For clockwise cyclic process work done is positive
