Wood and plastic are bad conductors of heat | Heat | Physics

Описание: Here we compare the behaviour of a metal spoon, a plastic scale and a wooden pencil placed in a glass of hot water. After some time, we see that the metal spoon has become hot at the top while the plastic scale and wooden spoon are still cool at the top. This tells us that wood and plastic are bad conductors of heat while metal is a good conductor of heat. This is why cooking utensils have wooden or plastic handles.
