STANDARD Physics Cyclic Processes MCQ Question
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 reversible.
The total heat absorbed by the system is not equal to work done by the system.
Change in internal energy is zero.
Correct Answer
Detailed Explanation
In a cyclic process, the system returns to its initial state. Since internal energy is a state variable, the change in internal energy (ΔU) is zero for a cyclic process.
