Do saucepans have plastic handles because plastics are good conductors of heat?

That's incorrect! Plastics are actually good insulators, not conductors, of heat. This is why they're used for saucepan handles.

Here's why:

* Heat conduction: Metals are excellent conductors of heat. They transfer heat quickly and efficiently.

* Heat insulation: Plastics are poor conductors of heat. They resist the flow of heat, keeping your hand safe from the hot metal of the pan.

So, the reason saucepans have plastic handles is to prevent you from burning your hand when holding a hot pan.
