Burt's mother asked him to use a spoon to stir the stew that was cooking on the stove. Which spoon will stay the coolest while he stirs and why?

Question 9 options:
An aluminum spoon because it can only be heated by radiation.
An iron spoon because it is a strong conductor of heat.
A wooden spoon because it is an insulator.
A silver spoon because it is an insulator.

Answered by admin @ 09/11/2021

Metals are good conductors of heat and electricity

Metals are good conductors due to presence of free electrons

They act as carrier to conduct heat or electricity.

Aluminum spoon will heat up as it is of metal

Iron spoon will heat up as it is of metal

Silver spoon will also heat up as it is of metal

Wood is a bad conductor of heat. It is an insulator

Wood has air space or pockets in its structure which makes it a bad conductor (it cannot conduct heat)

So a wooden spoon will be stay coolest as it is an insulator
