9. Changes in State

10. Thermal Energy/Heat/Temperature
Thermal Energy – the total amount of kinetic and potential energy of an object.
Heat – the movement of thermal energy from hot to cold. Heat always moves from hot to cold.
Temperature – the average kinetic energy of all the particles in an object.

11. Physical Properties

12. Physical vs. Chemical Properties

13. Physical Change vs. Chemical Change
Change in shape
Change in identity of the substance - rust

14. Physical Changes

15. Chemical Changes

16. Evidence of Chemical Change
Energy change
precipitate
Gas formed
Color change

17. Exothermic vs. Endothermic
Exothermic reaction - heat is released, becomes hot
Endothermic reaction - heat is absorbed, becomes cold
