1.	If Q, E and W denote respectively the heat added, change in internal energy and the work done by a closed cycle process, then
Answer» W=0 Q=W=0 E=0 Q=0 Solution :In cyclic process SINCE initial and final states are same internal energy is a STATE function therefore initial and final internal energies are also same but Q and W are not same during cyclic process. HENCE, E = 0.
