Question

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

Answer 1

During winters we prefer to wear more layers of clothes than wearing a single one because
the air gets trapped in the various layers and being a poor conductor of heat , there is no heat loss and so our body is warm.

hope this helps you...

Answer 2

During winters wearing more layers of clothing keeps us warmer because there are small pores inside the clothing thus it traps air as air is a bad conductor /insulator of heat it does not let heat escape from the clothing . Thus wearing more layers of clothing keeps us warmer than just wearing a thick piece of clothing .
