- A. Increasing the wall's thermal conductivity
- B. Increasing the wall's thickness
- C. Using a material with high specific heat capacity
- D. Using a material with high density
Answer
Increasing the wall's thickness
Explanation
The correct option is "Increasing the wall's thickness". Increasing the wall's thickness is right because it directly matches Energy transfers in a system: Required practical activity 2 (physics only): investigate the effectiveness of different materials as thermal insulators.. 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
Misunderstanding Thermal Insulation
Students often think that all materials are equally effective as thermal insulators without considering their thermal conductivity.
To fix this, students should investigate and compare the thermal conductivity of different materials to understand which ones are better insulators.
