Why are poor conductors of heat good insulators?
A good insulator is obviously a poor conductor.
An interesting fact is that poor conductors of electricity are also poor heat conductors.
Wood is a much better insulator than copper.
The reason is that metals that conduct electricity allow free electrons to roam through the material..
What are three examples of good conductors of heat?
Most metals are the good conductors of heat, Gold, Silver, Copper, Aluminium, Iron etc are good heat conductors as well as electrical conductors.
What are the bad conductors of heat?
Metals and stone are considered good conductors since they can speedily transfer heat, whereas materials like wood, paper, air, and cloth are poor conductors of heat. This tells us that wood and plastic are bad conductors of heat while metal is a good conductor of heat.

What are some insulators of heat?
Good Heat InsulatorsWood, plastic and air are some of the examples of heat insulators.Gases are poorest heat conductors. In other words, they are the best heat insulators. Air is a mixture of gases. This is why air is a good insulator.
