Conductors and
Insulators of Heat
Conductor:
An object that
allows heat energy
to flow freely
through it.
Examples:
•aluminum foil
•copper wire
•steel
• glass
• silverware
When do people use conductors
of heat?
Boil water
Cook Food
Can you think of more uses???
Insulator:
An object that
does not allow heat
energy to flow
freely through it.
Examples:
•plastic
•wood
•rubber
• cloth
• paper
When do people use insulators
of heat?
Coats/Jackets
Ice Chest
Oven mitts
Sometimes… Animals use stored fat

Temperature:
The measure of
heat in an
environment,
recorded in
degrees Celsius.
Boiling point:
The temperature
point at which a
liquid turns into a
gas. Boiling occurs
at 100° Celsius.
Freezing
point:
The temperature
point at which a
liquid turns into a
solid. Freezing
occurs at 0°
Celsius.
Melting point:
The temperature
point at which a
solid turns into a
liquid. Melting
occurs at 0°
Celsius.
Called Freezing Point if Decreasing Heat
Called Melting Point if Increasing Heat
Remember…
*Freezing goes from a
liquid to a solid
*Melting goes from
a solid to a liquid
