• It can travel high to low and low to high. 

The ability of a metal to allow heat or electricity to pass through it.

• conductivity
• insulator
• mass
• density

If the particles in a conductor are more tightly packed it will have a smaller conductivity

• TRUE

• FALSE

The best insulator would have...

• Loosely bound particles that are spread out.

• Tightly bound particles that are close together.

• Tightly bound particles and lots of free electrons.

• No particles at all, it would be a vacuum.

Calculate the payback time for double glazed windows that cost £1800 to install and save £150 on heating bills

• 14.4 months

• 22.5 years

• 0.083 years

• 12 years

Effective house insulation...

• ...has a low U-Value

• ...has a high U-Value

How does most insulation in the home work?

• The insulating material has a vacuum that doesn't allow conduction or convection to occur

• The insulating material has trapped air pockets that slows conduction and convection from occurring

• All the insulating material is put at the top of the house because heat rises

• All the insulating material is put in the walls because they have a large surface area
