Questions & Step-by-Step Solutions
In a cyclic process, the change in internal energy 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, must also 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.
