1. Thermal Energy

2. Thermal Energy is a measure of kinetic energy of an object It is the energy of ALL the moving particles in an object

3. Why does it feel like warm water is burning our hands if we run it over them when we come inside on a cold day?.

4. Thermal energy depends upon BOTH speed of the particles AND the amount of particles

5. Thermal energy, temperature and heat ARE NOT the same thing!

6. Temperature is a measure of the average speed of the particles in an object It depends upon kinetic energy

7. There are 3 scales that measure temperature FreezingBoiling Celcius0o100o Fahrenheit32o212o Kelvin273K373K

8. Heat is a TRANSFER of thermal energy between objects It is an ACTION! Heat moves from high to low; stops when both objects are the same temperature

9. Assuming both are boiling, Which has a higher temperature? Which has a higher THERMAL ENERGY?

10. Explain all the energy transfers that are occurring.

11. Conduction is a transfer of thermal energy when objects are touching

12. Radiation carries thermal energy through matter or space

13. Convection is transfer of thermal energy through a liquid or gas Convection carries thermal energy in currents (circular patterns)

14. Conduction vs Convection

16. thermal expansion
