Question
Why do we wear woolen clothes in winter?
✓

Answer

  1. The fibers of wool have the property of trapping air in between them.
  2. In trapping the air, woolen clothes do not allow the heat to flow away from the body, which would then become cold.
  3. Besides, wool is poor conductor of heat. So this property further prevents heat from leaving the body.
