Which materials are the best conductors of energy?

Which materials make the best insulators?

define thermal conductivity

How does the thermal conductivity of a material affect the rate of energy transfer through it by conduction?

What does the energy transfer per second through a layer of insulating material depend on?

How do you reduce the energy transfer as much as possible?

How does the thickness of a layer of material affect the rate of energy transfer by conduction through it?

Explain how conduction works.

Why is conduction faster in metals?

What is convection?

Explain how convection works.

What is a convection current and give examples.
