Question

discuss why wearing more layers of clothing during winter keeps us warmer than wearing just one thick piece of clothing?
​

Answer 1

Air is a poor conductor of heat. When we wear multiple layers of clothes, the air gets trapped between the clothing layers and prevents heat loss from our body. So, multiple layers keep us warmers as compared to a single layer.....

Answer 2

Answer:

If we are given the choice in winter of using either one thick woollen blanket or two thin woollen blankets joined together, then we should prefer two thin woollen blankets joined together. This is because the two thin woollen blankets joined together will have a layer of air trapped in-between them. And this extra layer of trapped air (being a very poor conductor of heat) will prevent our body heat from going away to the cold air more efficiently and hence keep us more warm. The single, thick woollen blanket does not have this extra layer of air in it. In fact, wearing more layers of clothes keeps us warmer in winter than wearing just one thick piece of clothing.
