The system which can exchange matter as well as energy with its surroundings is called____________?
Correct answer: A. open system
- A. open system
- B. Closed system
- C. Isolated system
- D. Inert system
Explanation
An open system can exchange both matter and energy with its surroundings, such as steam flowing through a turbine. A closed system can exchange energy but not matter, so it is the likely alternative selected through confusing energy exchange with matter exchange.

About First Law of Thermodynamics
The first law relates heat supplied, work done and the change in internal energy through energy conservation. Problems use sign conventions and apply the law to isothermal, adiabatic, isobaric and isochoric processes. Internal energy is a state function, while heat and work depend on the path followed.
