Paloma Berger · Answer 1

It will feel hot.

Explanation:

The part of the metal that has been sitting in the sun will heat up, and because metal is a good conductor, the part sitting in the sun will heat up the part sitting in the dark.

We say metal is a good conductor because it has high thermal conductivity, which mean heat will flow from the hot section of the bar to the cold section of the bat.
