Question

A teacher describes a woollen cloth as a bad conductor of heat. A student tries to test this by trying to wear a woollen coat in the summer. He feels very hot and has to take it off. What explanation can be offered to the student to explain why wool is a bad conductor?​

Answer 1

Answer:

Cotton clothes are thin and do not have space in which air can be trapped. Thus, cotton clothes do not prevent heat coming out of our body. Woollen clothes keep us warm during winter because wool is a poor conductor of heat and it has air trapped in between the fibres.
