1. Matter in Motion - all thing are made of tiny particles (atoms)
- particles are in constant and random motion in all directions and different speeds
Due to the movement of particles ALL matter
has kinetic E
Kinetic Energy (KE)
E due to movement
the objects mass and velocity determines
the KE of any matter

2. TEMPERATURE
Is the measure of the AVERAGE Kinetic Energy of the particles that make up that object

3. Thermal Energy is the energy that comes from heat
heat is generated by the movement of tiny particles within an object.
The faster these particles move, the more heat is generated
Energy that comes from temperature of matter

4. Conduction
Transfers thermal E with collisions between particles due to heat
Occurs because particles are in constant motion
Transfers E without transferring matter
Occurs faster in solids and liquids (due to closeness)
Metals are best conductors

5. Convection Occurs in fluids
More energetic particles move from one place to another
Substance expands (becomes less dense) when temp rises
Substance condenses (becomes more dense) when temp decreases

6. Convection cont.
FLUID Is a substance that has no fixed shape and forms easily to external containment in a gas or a liquid. CONVECTION CURRENT Thermal heat moves from warmer parts of fluid to cooler parts

7. Radiation
Transfer of E through electromagnetic waves such as light and microwaves
Travel through space even if no matter is present
When radiation strikes a material it absorbs, reflects, or transmits same E

8. Thermal Energy- DRAW THIS

9. Your assignment
State an example of each conduction, convection, and radiation
Explain why you chose that example and not something else
