Why does a metal spoon handle gets hot in soup but a plastic spoon handle does not?

A metal spoon handle gets hot in soup because metal is a good conductor of heat, meaning it can easily transfer heat from the hot soup to the handle. On the other hand, plastic is a poor conductor of heat, so it does not easily transfer heat from the soup to the handle of a plastic spoon. This is why a metal spoon handle will feel hotter to the touch compared to a plastic spoon handle when used in hot soup.
