Q: In a cyclic process, the net work done is equal to: (2020)
Solution: In a cyclic process, the net work done is equal to the net heat added to the system, as the internal energy returns to its initial state.
Steps: 6
Step 1: Understand what a cyclic process is. A cyclic process is when a system goes through a series of changes and returns to its original state.
Step 2: Recognize that in a cyclic process, the internal energy of the system does not change because it ends up where it started.
Step 3: Know that the first law of thermodynamics states that the change in internal energy is equal to the heat added to the system minus the work done by the system.
Step 4: Since the internal energy returns to its initial state in a cyclic process, the change in internal energy is zero.
Step 5: Therefore, the heat added to the system is equal to the work done by the system.
Step 6: Conclude that in a cyclic process, the net work done is equal to the net heat added to the system.
