Question

we feel warm if we wear woolen clothes in winter why

Answer 1

good evening bro here is your answer

We wear woollen clothes in winter because air is a poor conductor of heat and woollen clothes do not allow the transfer of body heat to the environment and keep us warm. Woolen yarn has large amount of air trapped between its crimps.

Answer 2

because it traps heat in it so we feel that woolly clothes are warmer in winter and it is also warmer in summers
