- C. The ability of a material to insulate against heat
- D. The ability of a material to absorb sound
Answer
The ability of a material to transfer heat energy
Explanation
The correct option is "The ability of a material to transfer heat energy". The ability of a material to transfer heat energy 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.
