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

If Q E And W Denote Respectively The Heat Added Physics Question

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.
