Question: In a cyclic process, the change in internal energy of the system is:
Options:
Positive
Negative
Zero
Depends on the work done
Correct Answer: Zero
Solution:
In a cyclic process, the system returns to its initial state, so the change in internal energy is zero.

Questions & Step-by-Step Solutions
In a cyclic process, the change in internal energy of the system is:
Correct Answer: Zero
Step 1: Understand what a cyclic process is. A cyclic process is when a system goes through a series of changes and eventually returns to its starting point.
Step 2: Recognize that internal energy is a property of the system that depends on its state.
Step 3: Since the system returns to its initial state in a cyclic process, all properties, including internal energy, return to their original values.
Step 4: Therefore, the change in internal energy, which is the difference between the final and initial states, is zero.
Cyclic Process – A thermodynamic process where the system returns to its initial state, resulting in no net change in internal energy.
Internal Energy – The total energy contained within a system, which depends on the state of the system.
