- A. Metal
- B. Wood
- C. Glass
- D. Styrofoam
Answer
Styrofoam
Explanation
Styrofoam is an insulating material with low thermal conductivity, making it effective at reducing heat transfer.
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.
