Question
- A. It slows down energy transfer
- B. It has no effect on energy transfer
- C. It speeds up energy transfer
- D. It completely stops energy transfer
Answer
It speeds up energy transfer
Explanation
The correct option is "It speeds up energy transfer". It speeds up energy transfer is right because it directly matches Energy transfers in a system: Describe how thermal conductivity affects the rate of energy transfer by conduction.. 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 with wall thickness
Students often think that a material’s thermal conductivity alone determines how quickly heat passes through a wall, ignoring the role of wall thickness.
Explain that the rate of heat transfer by conduction is proportional to the material’s thermal conductivity but inversely proportional to the wall’s thickness; both properties together determine the overall heat transfer rate.
