Magine that you have a metal bar sitting half in the Sun and half in the dark. On a sunny day, the part of the metal that has been sitting in the Sun feels hot. If you touch the part of the metal bar that has been sitting in the dark, will it feel hot or cold?

The metal will feel hot.

Explanation:

Metals are known for their high thermal conductivity. If one part of the metal feels hot, the other will as well.

This piece of metal has been exposed to the sun, and will feel hot after a certain amount of time. By the statement above, the unexposed part will feel hot as well.

Hope that helps!
