Question

Why are two thin blankets piled together warmer than a single one of the same total thickness as the two? *

Air that is trapped between the layers of the blanket acts as a poor conductor.
The outer thin blanket transfers heat faster.
Air acts as medium to transfer the energy.
There is a decrease in the sensation of touch

Answer 1

Explanation:

Two thin blankets usually warmer than one thick blanket because air is trapped between them. And the air is bad conductor of heat. It does not pass heat from our body to the surroundings.
