Questions & Step-by-Step Solutions
In a thermodynamic cycle, the net work done is equal to which of the following?
Step 1: Understand that a thermodynamic cycle is a series of processes that return a system to its initial state.
Step 2: Recall the first law of thermodynamics, which 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 3: In a complete cycle, the change in internal energy is zero because the system returns to its initial state.
Step 4: Since the change in internal energy is zero, the heat added to the system must equal the work done by the system.
Step 5: Therefore, the net work done in a thermodynamic cycle is equal to the net heat added to the system.
