Question
- A. A battery powering a light bulb
- B. A car engine losing heat to the environment
- C. A closed thermos bottle maintaining the temperature of its contents
- D. A solar panel converting sunlight into electricity
Answer
A closed thermos bottle maintaining the temperature of its contents
Explanation
The correct option is "A closed thermos bottle maintaining the temperature of its contents". A closed thermos bottle maintaining the temperature of its contents is right because it directly matches Energy transfers in a system: Describe examples of energy transfers in a closed system with no net change to total energy.. The other options are less suitable because they change the required Physics relationship, confuse the relevant energy store or use a distractor that does not answer the question.
Common mistake
Misunderstanding Closed Systems
Students often think that energy can be created or destroyed in a closed system.
Emphasize that in a closed system, energy is conserved and can only be transferred or transformed, not created or destroyed.
