Question

If you touch the metal sides in an oven with your bare hand, you're in trouble. But hold your hand briefly in the oven air and you're okay. What does this tell you about the relative conductivities of metal and air?

Answer 1

Answer:

Metal is a good conductor of heat but air is a poor conductor of heat.

Explanation:

Touching the metal sides of the oven can be harmful while holding our hand briefly in the oven air is okay. This tells us about the relative conductivities of metal and air that metal is a good conductor of heat but air is a poor conductor of heat. Conduction is the transference of heat through physical contact. Not all materials conduct heat in the same way. The best conductors of heat are metals and stone.
