- A. To ensure buildings are aesthetically pleasing
- B. To minimize energy costs and improve comfort
- C. To increase the weight of the building materials
- D. To enhance the structural integrity of the building
Answer
To minimize energy costs and improve comfort
Explanation
The correct option is "To minimize energy costs and improve comfort". To minimize energy costs and improve comfort 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.
