Question

We wear a number of garments during winter rather than one thick garment. Why? ​

Answer 1

Explanation:

During winters, we prefer wearing more layers of clothing than just one thick piece of clothing because air gets trapped in between the various clothing layers. Being a poor conductor of heat, air prevents heat loss from our body. Hence, layers of clothing keep us warmer than a single layer.

Answer 2

Explanation:

When we wear a number of garments, there are extra layers of air trapped between each garment which acts as insulator and does not allow the heat from the body to flow out. Thus we feel more warm and comfortable by wearing a number of garments than wearing a thick single garment.
