  1. Chapter 6: Section 2 Temperature

  2. What is temperature? • Any ideas? • Think, pair, share(1min)

  3. 2 things you need to know: • All things are made of atoms or particles that are too small to see

  4. 2. The particles are always moving in all directions.

  5. Particle Movement in a Solid, Liquid, Gas • Students as particles demo

  6. Back to Temperature The measure of kinetic energy of the particles in an object Kinetic energy of particles Temperature =

  7. Measuring Temperature • 2 ways: • Fahrenheit Scale: At what temp does H2O freeze?________ At what temp does H2O boil?____

  8. Measuring Temperature 2. Celcius Scale: At what temp does water freeze?_____ At what temp does water boil?_____

  9. What is heat? • Think about this: • What happens to your hand when you grab a cold drink out of the fridge?

  10. Heat • The transfer of energy from one object to another • Flows from warmer to cooler objects

  11. Let’s go back to this situation Knowing what you know about heat…think about this: • What happens to your hand when you grab a cold drink out of the fridge?

  12. Midpoint Review • How are temperature and kinetic energy related? • Heat is transferred how?

  13. Heat Transfer • There are 3 types: • Conduction • Convection • Radiation

  14. Conduction Transfer of energy by collisions of molecules in a material (2 things touching) Usually happens in solids

  15. Conduction

  16. Which spoon would you rather cook with? metal wooden Metal is a good conductor

  17. Insulators • Some things are bad conductors • They can be used as insulators • Sweaters • Blankets • Plastics • Wood • rubber

  18. Convection • Heat is transferred between objects of different temperatures • Most common in gases and liquids

  19. Examples of Convection Birds can float with out flapping wings Heating your home

  20. Radiation • Transfer of heat energy by waves

  21. Examples of Radiation • Heat from fire • Microwave heating food

  22. Heat • BrainPop

  23. Quick Review • Heat is transferred from ______ things to _______things. • What are the 3 types of heat transfer? • This is more common in solids____ • This is more common in liquid/gas_
