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

A

E = 0

B

Q = 0

C

W = 0

D

Q = W = 0

Text Solution

Verified by Experts

The correct Answer is:
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.
