When does the internal energy of a system change in thermodynamics?

Options

  1. AWhen work is done by the system
  2. BWhen heat is added to the system
  3. CWhen matter enters or leaves the system
  4. DAll of the above

Correct answer

D. All of the above

Step-by-step solution

The internal energy of a system in thermodynamics changes when heat is added to or removed from the system, when work is done on or by the system, and when matter enters or leaves the system.
