Question

It is preferred to use two thin blankets rather than one thick blanket. Explain the reason. [HOTS]

Answer 1

Explanation:

There is a layer of air in between the blankets. Since air is bad conductor of heat prevent body heat to escape out, two thin blankets provides more heat than one thick blanket.

Answer 2

It's because when you add two layers, there is always air trapped between the two blankets and that acts as an additional insulation. Since air is an insulator of heat, it prevents the escape of body heat. That is why two thin blankets are usually warmer than one thick blanket.
