dear raghul 
there is no attachment in the question , so, about which process you are talking about ?? 
kindly be specific . 
and workdone is considered to be 0 in cyclic process as the initial and final positions are identical , but thats just for convention and not true . 
WAITING TO HEAR FROM YOU AGAIN , 
all the best
