In a cyclic process , the change in internal energy of the system is
(A) zero, Q = –W
(B) zero, Q = W
(C) Q, ΔEint = –W
(D) Q, ΔEint = W
The answer is: (B) zero, Q = W
In a cyclic process , the change in internal energy of the system is zero and Q=W. Where Q is heat transferred to the system and W is work done by the system.
