1. Intro to Heat
Mr. Oey

2. Heat
Heat is kinetic energy in a substance. Heat is the motion of the molecules in a substance, not the motion of the substance itself.
Energy that flows between two objects because of a difference in temperature. For example, a metal spoon in hot water.

3. Measuring Heat Celsius Fahrenheit Freezing: 0 degrees
Boiling: 100 degrees
Freezing: 32 degrees
Boiling: 212 degrees

4. Heat Movement
Molecules move from places of higher temperatures to places with lower temperatures

5. Thermal Equilibrium
Molecules move from warm to cold until they reach a balanced temperature
This balance is called thermal equilibrium.

6. Insulators & Conductors
6th Grade Science

7. Vocabulary Insulator Conductor
an object that reduces the transfer of heat
an object that easily allows the transfer of energy

8. Expansion & Contraction

9. Vocabulary
Solid
particles vibrate in one place
Liquid
particles spin and move closely together
Gas
particles spin and move fast and far away from each other

10. Vocabulary Expansion Contraction
as molecules are heated they spread out as they move around quickly and cause objects to become larger (expand)
Heating = Bigger
as molecules are cooled they move closer together and cause objects to shrink (contract)
Cooling = Smaller

11. Heat Transfer
Kinetic Energy

12. Vocabulary Conduction
the transfer of heat by direct contact between solids
Convection
Transfer of heat in liquids & gases
Heat rises
Radiation
Transfer of heat in empty space w/o any particles

13. Examples Conduction A pot heating on a stove Convection Boiling water
Heating a home
Radiation
Sun’s rays heating a car
