Question

Explain how, woolen clothes keep us warm during cold winter days.Discuss why, wearing more layers of clothing during winter keeps warmer than wearing just one thick piece of clothing.

Answer 1

Woollen clothes doesn't allow atmospheric air to touch the body.. So it feels hot in winter.. And sweating in summer

Answer 2

wollen clothes keeps us warm in winter season because it have not much space between them and the heat can't exaust from our body and air present outside can't be in contanct to the body. And we wear one less thicked cloth then, it have many small holes from which heat is released and outside air be in contact with the body and hence it can't warm more.
