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

Questions & Step-by-Step Solutions
In a cyclic process, what is the net change in internal energy?
Correct Answer: 0
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, are the same as they were at the beginning.
Step 4: Conclude that because the initial and final states are the same, the net change in internal energy is zero.
Cyclic Process – A process in which a system undergoes a series of changes and 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.
