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

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

States Changes Matter Matter can change states

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

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

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

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

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

 Water  ice

 Freezing  Water  water vapor

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

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

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

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

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

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

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

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

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

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

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
