Which of the following statements about internal energy is correct?

Options

  1. AIt only includes mechanical energy.
  2. BIt does not change when matter enters or leaves the system.
  3. CIt is a state function.
  4. DIt depends on the surroundings.

Correct answer

C. It is a state function.

Step-by-step solution

Internal energy is a state function in thermodynamics, meaning it depends only on the state of the system and not on the path taken.
