Woollen cloth protects the body from cold because
It is a good conductor of heat
It is a poor conductor of heat
External heat rays enter into the body through the woollen cloth
It reflects heat
It is a poor conductor of heat
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.
