Question: In a cyclic process, the net work done by the system is equal to:

Options:

  1. The net heat added to the system
  2. The change in internal energy
  3. The heat lost by the system
  4. Zero

Correct Answer: Zero

Solution:

In a cyclic process, the net work done by the system is zero because the system returns to its initial state.

  4. Zero

Questions & Step-by-Step Solutions

In a cyclic process, the net work done by the system is equal to:
  • 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 in a cyclic process, all the energy and work done during the process will balance out.
  • Step 3: Realize that since the system returns to its initial state, the total change in energy is zero.
  • Step 4: Conclude that because the energy change is zero, the net work done by the system must also be zero.
  • Cyclic Process – A process in which a system undergoes a series of changes and returns to its initial state, resulting in no net change in internal energy.
  • Work Done in Thermodynamics – The work done by a system during a process is related to the area enclosed by the process path on a pressure-volume diagram.
