A system in which there is exchange of energy but not of mass, is called a/an ____________ system?
Correct answer: D. Closed
- A. Isolated
- B. Open
- C. Insulated
- D. Closed
Explanation
A closed system can exchange energy as heat or work but cannot exchange mass with its surroundings. An isolated system exchanges neither mass nor energy, so it is not the correct choice.
