Question
- A. It increases the rate of cooling.
- B. It decreases the rate of cooling.
- C. It has no effect on the rate of cooling.
- D. It only affects the temperature inside the building.
Answer
It decreases the rate of cooling.
Explanation
The correct option is "It decreases the rate of cooling.". It decreases the rate of cooling. 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.
