Go with the Flow...of Heat!
Heat moves from through some materials very easily
A material that allows heat to move through it easily is called a conductor.
Many heat conductors also conduct electricity well.
Solids are better conductors of heat than liquids or gases are
Because the particles of a solid are packed tightly together, heat can move quickly from one particle to another.

Glass does not conduct heat well. If you pour boiling water into a metal bowl, the outside of the bowl quickly gets hot. A glass bowl gets warm more slowly.
4
Marble does not conduct heat as well as metals do. But it can still conduct heat away from your body. That’s why marble feels cool when you touch it.
5
Metals are great heat conductors! Some metals conduct heat better than others do.

Heat Proofing a Home
When the weather is hot, you want to keep heat from coming into your home.
When the weather is cold, you want to keep heat from leaving your home.
It costs money to cool and heat a home!

1.Insulation
Insulation is blown inside the walls of a house. Insulation keeps heat from traveling through to the attic.
16
2.Windows
These windows have two panes of glass to limit conduction. They also have a coating that limits heat radiation.
17
3.Pipes
Hot pipes radiate heat from water into the air. Wrapping them keeps the heat from escaping.

4.Soil
Soil is a great insulator. Basements are usually cool, even in the summer.
