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.
