If Q, E and W denote respectively the heat added, change in internal energy and the work done in a closed cycle process, thenA. E = 0B. Q = 0C. W = 0D. Q = W = 0

If Q, E and W denote respectively the heat added, change in internal e

1.	If Q, E and W denote respectively the heat added, change in internal energy and the work done in a closed cycle process, thenA. E = 0B. Q = 0C. W = 0D. Q = W = 0
Answer» Correct Answer - A 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. So change in internal energy is zero hence E = 0.
