A system that can exchange or transfer both energy and matter with the surroundings is:
Correct answer: C. Open system
- A. Isolated system
- B. Closed system
- C. Open system
- D. Adiabatic system
Explanation
An open system can exchange both energy and matter with its surroundings. The stovetop example would be an open system because heat and water vapor can be lost to the air.
