why wearing more layers of clothing during winter keeps us wrmer than wearing just one thickpiece of clothing?
This is because...when wearing more layer of clothes...the warmth of our body is trapped inside tht and it doesn't allow it to pass outside of our body....when we wear a thick piece oif cloth in winters we feel cold because...the thick piece of cloth cannot trap the warmth of our body....
More layer of clothing keeps us warm because there is a layer of air trapped between the two layers which keeps us warm, but when we wear a single piece of clothing there is no layer of air trapped between the two layers so it keeps us cooler than wearing more layers of clothing.
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.
Hope this helped you :)
