Question

Boojho is wondering why a cotton garment cannot keep us as warm in winter as a woollen sweater does

Answer 1

hey mate here is ur ans

we know that air is a bad 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 thick layers of fibres thus prevent the loss of heat from our body to outside cold environment

hope it helps you
