Why a wooden spoon does not get hot when used for stirring liquids?

This is not true. A wooden spoon does get hot when used for stirring liquids, however, it does not get as hot as a metal spoon. This is because wood is a poor conductor of heat, meaning that it does not transfer heat well. Metal, on the other hand, is a good conductor of heat, so it transfers heat quickly and easily. This is why a metal spoon gets hotter than a wooden spoon when used for stirring liquids.
