1. Warm up 1. Are fossil fuels renewable or nonrenewable? Why? 2. Where do fossil fuels get their energy from? 3. What are some examples of fossil fuels?

2. Heat/Temperature

3. Temperature: Measure of the AVERAGE KINETIC ENERGY of the particles Depends upon KINETIC energy

4. How do we measure temperature?

5. 3 Scales: Fahrenheit Celsius Kelvin

6. What is absolute zero?

7. Thermal energy: TOTAL energy of the PARTICLES in an object

8. TE depends on TEMPERATURE AND AMOUNT of particles

9. SO… Which has a higher temperature? Which has more TE? Why?

10. Explain the energy transfer shown below:

11. Transfer of THERMAL energy TE always moves from higher- temperature to lower-temperature Heating stops when the objects are the same temperature

12. Conduction Transfer of TE when objects are touching

13. Radiation Transfer of TE through matter or space as EM waves (ex: visible light, infrared, etc) Where can we see examples of this?

14. Convection Transfer of thermal energy by the movement of liquid or gas How exactly does this work? Where can we see examples of this?

15. Problems: Use your textbook, page 153, to answer the following: 1. 24 o C to _____ o F 2. 17 o C to _____ o F 3. -4 o F to _____ o C 4. 98.6 o F to _____ o C
