Conservation and dissipation of energy

Question

A. It increases energy loss
B. It reduces energy efficiency
C. It helps maintain a comfortable temperature
D. It increases the cost of heating

Answer

It helps maintain a comfortable temperature

Explanation

The correct option is "It helps maintain a comfortable temperature". It helps maintain a comfortable temperature 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.
