Question

how do woollen
cloth keep us warm in winter

Answer 1

Wollen clothes trap the heat of body our body and holds it and keeps our body warm. If you wear more than one or two layer of cloth it will be warmer than wearing a thick Wollen cloth as it captures the heat and Stores it between the layer of clothing instead of only wearing one layer of Wollen clothing.

wool is a good insulator it absorbs heat easily and dissipates it slowly it also stops the outer cold temperatures to influence the inner heat hence it keeps us warm in low temperatures....
