If Q, E and W denote respectively the heat added, change in internal energy and the work done in a closed cyclic process, then:
Options
(a) W = 0
(b) Q = W = 0
(c) E = 0
(d) Q = 0
Correct Answer:
E = 0
Explanation:
In a cyclic process, the initial state coincides with the final state. hence, the change in internal energy is zero, as it depends only on the initial and final states. But Q and W are non-zero during a cycle process.
