Type: MCQ-conceptual-Easy-Class 11
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 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.
Correct Answer
Option D
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.
