Topic: Bad Conductors of Heat.

Why are two thin blankets warmer than one thick blanket?

Because two chocolates are better than one.

No.

To understand this, we need to first learn about bad conductors of heat.

Bad conductors of heat are the materials which do not allow heat to easily flow through them.

Air, wood and glass are some examples of bad conductors of heat.

In these examples, is our train conductor included as well?

Just listen.

A thick blanket allows much of our body heat to escape into the atmosphere.

However, when we use two blankets one on top of the other, air gets trapped between them.

This air being a bad conductor of heat.

Does not allow our body heat to easily flow into the atmosphere, thus keeping us warm.
