Question
- A. They reflect more heat
- B. They have lower thermal conductivity
- C. They trap air inside
- D. They absorb more heat
Answer
They have lower thermal conductivity
Explanation
The correct option is "They have lower thermal conductivity". They have lower thermal conductivity is right because it directly matches Energy transfers in a system: Describe how wall thickness affects the rate of cooling of a building.. 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 Wall Thickness Impact
Students often think that increasing wall thickness always leads to slower cooling rates without considering other factors like material properties.
Explain that while thicker walls can reduce cooling rates, the thermal conductivity of the material also plays a crucial role in determining the overall rate of cooling.
