Question

In a cyclic process, which of the following statement is not correct?

• A. Change in internal energy is zero.
• B. The system returns to its initial state and it is reversible
• C. The total heat absorbed by the system is equals to work done by the system.
• D. Change in internal energy is not zero.

Answer 1

Answer: (D)

Change in internal energy is not zero.

Answer 2

: in a cyclic process, the system returns to its initial state. Since internal energy is a state variable

$\therefore \Delta U = 0$for a cyclic process.
