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?
