If Q, E and W denote respectively the heat added, change in internal energy and the work done in a closed cycle process, then

Options

A. E = 0
B. Q = 0
C. W = 0
D. Q = W = 0

Answer

A

Explanation

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.
