Q: In a cyclic process, the net work done is equal to the:
Solution: In a cyclic process, the net work done is equal to the heat added to the system.
Steps: 8
Step 1: Understand what a cyclic process is. A cyclic process is a series of changes that return a system to its original state.
Step 2: Know that in a cyclic process, the system goes through different states but ends up where it started.
Step 3: Remember that work done by the system is the energy transferred when the system changes state.
Step 4: Recognize that heat is energy transferred due to temperature difference.
Step 5: In a cyclic process, the net work done is the total work done by the system minus the total work done on the system.
Step 6: Realize that the first law of thermodynamics states that the change in internal energy of a system is equal to the heat added to the system minus the work done by the system.
Step 7: Since the internal energy returns to its original value in a cyclic process, the change in internal energy is zero.
Step 8: Therefore, the net work done in a cyclic process is equal to the heat added to the system.
