Question

In a cyclic process, which of the following statement is correct? (A) Change in internal energy is not zero (B) The system returns to its initial state and it is is reversible (C) The total heat absorbed by the system is not equal to work done by the system (D) Change in internal energy is zero

In a cyclic process, the system returns to its initial state. Since internal energy is a state variable, ∴ Δ U = 0 , for a cyclic process.

Q. In a cyclic process, which of the following statement is correct?

Change in internal energy is not zero

The system returns to its initial state and it is is reversible

The total heat absorbed by the system is not equal to work done by the system

Change in internal energy is zero

In a cyclic process, the system returns to its initial state. Since internal energy is a state variable,
$∴ Δ U = 0$ , for a cyclic process.
