Question

Air trapped in the fur of the caribou’s coat functions as _____.

Answer 1

it functions as insulation, to keep it warm

Answer 2

insulation

Step-by-step explanation:

Conductivity represents the degree of ease through which heat is transmitted through a material.

Any substance that has a high conductivity i.e., can pass heat easily is called a conductor of heat.

Any substance that has a low conductivity i.e., cannot pass heat easily is called a insulator of heat.

Air does not conduct heat well. So, it acts an insulator and traps heat.
