Question

how does woollen clothes keep is warm

Answer 1

Woolen clothes keep us warm in wimter seasons as they are knitted tightly and due to which cold air does not enter our body due to which we feel warm and comfortable.

Answer 2

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. Wollen clothes keep us warm during winter because wool is a poor conductor of heat and it has air trapped in between the fibres......... plz mark me as brainlist..
