1. States Changes Catalyst What happens to an ice cube when you hold it in your hand? What happens when you boil water?

2.  What are the 3 main states of matter?  Solid  Liquid  Gas  Matter can change from one state to another.

3. States Changes Matter Matter can change states

4.  In order to move from one state of matter to another, energy must be added or removed.

5. States Changes MatterMatter can change states Changing States To change states, energy must be added or removed

6.  When energy is added, the following changes might occur:  Solid  liquid  Liquid  gas  Solid  gas

7.  When energy is removed, the following changes might occur:  Gas  liquid  Liquid  solid  Gas  solid

8. States Changes MatterMatter can change states Changing States To change states, energy must be added or removed Adding Energy Solid  liquid Liquid  gas Solid  gas Removing Energy Liquid  solid Gas  liquid Gas  solid

9.  What are the 3 forms of water?  Liquid: water  Solid: ice  Gas: water vapor

10.  Water  ice

11.  Freezing  Water  water vapor

12.  Water  ice  Freezing  Water  water vapor  Evaporation  Water vapor  water

13.  Water  ice  Freezing  Water  water vapor  Evaporation  Water vapor  water  Condensation

14.  Water  ice  Freezing  Water  water vapor  Evaporation  Water vapor  water  Condensation  Ice  water

15.  Water  ice  Freezing  Water  water vapor  Evaporation  Water vapor  water  Condensation  Ice  water  Melting  Ice  water vapor

16.  Water  ice  Freezing  Water  water vapor  Evaporation  Water vapor  water  Condensation  Ice  water  Melting  Ice  water vapor  Sublimation  Water vapor  ice

17.  Water  ice  Freezing  Water  water vapor  Evaporation  Water vapor  water  Condensation  Ice  water  Melting  Ice  water vapor  Sublimation  Water vapor  ice  Deposition

18. MELTING  SOLID  LIQUID  As energy is added, the temperature increases  Particles begin to move faster and away from each other EVAPORATION  LIQUID  GAS  As energy is added, the temperature increases  Particles move even faster and more away from each other

19. SUBLIMATION  SOLID  GAS  As a lot of energy is added, the temperature increases rapidly  Particles move very fast very quickly  Changes from solid to gas without going through liquid state

20. States Changes Adding EnergyEnergy, temperature, particles move apart. Melting: Solid  liquid Evaporation: Liquid  gas Sublimation: Solid  gas, no liquid state

21. FREEZING  LIQUID  SOLID  As energy is removed, the temperature decreases  Particles begin to move slower CONDENSATION  GAS  LIQUID  As energy is removed, the temperature decreases  Particles move even slower

22. DEPOSITION  GAS  SOLID  As a lot of energy is removed, the temperature decreases rapidly  Particles slow down quickly  Changes from gas to solid without going through liquid state

23. States Changes Adding EnergyEnergy, temperature, particles move apart. Melting: Solid  liquid Evaporation: Liquid  gas Sublimation: Solid  gas, no liquid state Removing Energy Energy, temperature, particles move slower. Freezing: Liquid  solid Condensation: Gas  liquid Deposition: Gas  solid, no liquid state

24. GASLIQUIDSOLID Energy is removed Energy is added

26. LIQUID GAS SOLID Energy is removed Energy is added

27. States Changes Adding & Removing Energy LIQUID GAS SOLID Energy is removed Energy is added
