Which property defines an open thermodynamic system?
Answer and explanation
Correct answer: D. Can exchange both matter and energy with its surroundings
- Step 1: By thermodynamic classification, systems are open, closed, or isolated. Step 2. An open system allows both mass and heat/work transfer across its boundary. Answer: Can exchange both matter and energy with its surroundings. Why not the others: Closed system exchanges energy but not matter; isolated system exchanges neither; matter exchange without heat violates physical boundaries.
