1. Heat Transfer

2. Remember!!!!!
Heat is the movement of thermal
energy from hot to cold

3. The Nature of Heat
Heat Moves One Way
Heat always moves from hot to cold
until both are equal/ equilibrium is reached

4. How is Heat Transferred?
The Nature of Heat
How is Heat Transferred?
Conduction Convection Radiation

5. Read & Annotate pages 458 – 459 in the textbook.
Assignment
Read & Annotate pages 458 – 459 in the textbook.
As you read make sure to circle “blah” words, circle, highlight or start important information.
Write down AT LEAST 4 statements from the reading that you feel are the most important

6. The Nature of Heat
Conduction, Heat is transferred
from one particle of matter to another within an object or between 2 objects (solid to a solid – objects are touching)
Ex: heat travels through metal

7. How does the demo demonstrate conduction?

8. Convection is heat transfer that occurs in fluids – gasses & liquids
The Nature of Heat
Convection is heat transfer that occurs in fluids – gasses & liquids
circular movement that transfers heat w/in the liquid or air
Ex. if you watch a pot of hot water on a stove, you will see the water moving

9. How does the demo demonstrate convection?

10. The Nature of Heat
Radiation is the transfer of energy
by electromagnetic waves
Does not require matter
How heat travels to us from the sun.
You can feel radiation from a bonfire

11. How does the demo demonstrate radiation?
