Question
- A. To increase the amount of light entering the building.
- B. To reduce energy loss and maintain temperature.
- C. To enhance the aesthetic appearance of the walls.
- D. To provide structural support to the building.
Answer
To reduce energy loss and maintain temperature.
Explanation
The correct option is "To reduce energy loss and maintain temperature.". To reduce energy loss and maintain temperature. is right because it directly matches Energy transfers in a system: Explain how thermal insulation reduces unwanted energy transfers by heating.. 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 Thermal Insulation
Students often think that thermal insulation completely prevents heat transfer instead of reducing it.
Emphasize that thermal insulation slows down the rate of heat transfer, making it less effective but not eliminating it.
