Question

A. It slows down the cooling rate
B. It has no effect on the cooling rate
C. It speeds up the cooling rate
D. It makes the building warmer

Answer

It speeds up the cooling rate

Explanation

The correct option is "It speeds up the cooling rate". It speeds up the cooling rate is right because it directly matches Energy transfers in a system: Describe how thermal conductivity of wall materials 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

Confusing Thermal Conductivity

Students often confuse thermal conductivity with insulation effectiveness, thinking that higher thermal conductivity means better insulation.

Remember that higher thermal conductivity means materials transfer heat more easily, which is not ideal for insulation. Lower thermal conductivity is better for reducing heat loss.
