  1. States of Matter Earth Science Intro Unit

  2. I will be able to define and describe matter and the three states of matter. What are the states of Matter? • Matter • All matter is made of atoms. • Atoms in constant motion. • Particle movement determines the state of matter. • States of Matter. • Solid • Liquid • Gas

  3. I will be able to define and describe matter and the three states of matter. What are the states of Matter? • Solids • Shape: • Definite • Volume: • Definite • Atoms: • Very close together. • Vibrate in place. • Exception: • Water, ice has more space between atoms than liquid water.

  4. I will be able to define and describe matter and the three states of matter. What are the states of Matter? • Liquids • Shape: • Not definite • Volume: • Definite • Atoms: • Further apart • Move, have more kinetic energy.

  5. I will be able to define and describe matter and the three states of matter. What are the states of Matter? • Gases • Shape: • Not definite • Volume: • Not Definite • Atoms: • Moving very fast. • Most kinetic energy. • Move faster when heat is applied. • Move slower when heat is taken away.

  6. I will be able to explain what a change in state is and describe how matter changes state. What is a change in State? • Changes in States • A change of a substance from one physical state to another. • Examples: • Water vapor to liquid water. • Liquid water to ice.

  7. I will be able to explain what a change in state is and describe how matter changes state. What is a change in State? • Energy Gained or Lost • To change state, energy must be added or removed. • Gaining or losing energy changes the temperature of a substance.

  8. I will be able to explain what a change in state is and describe how matter changes state. What happens to matter when a change of state occurs? • Energy / Motion of Particles. • Energy of the particles change. • The speed and the distance between particles change.

  9. I will be able to explain what a change in state is and describe how matter changes state. What happens to matter when a change of state occurs? • Energy / Motion of Particles. • Solids • Vibrate in place, particles close together

  10. I will be able to explain what a change in state is and describe how matter changes state. What happens to matter when a change of state occurs? • Energy / Motion of Particles. • Liquids • Move around • Particles further apart.

  11. I will be able to explain what a change in state is and describe how matter changes state. What happens to matter when a change of state occurs? • Energy / Motion of Particles. • Gas- • Move quickly • Particles very far apart.

  12. I will be able to explain what a change in state is and describe how matter changes state. What is a change in State? • Melting • Solid becomes liquid. • Energy is added • Particles speed up. • Temperature rises • Melting point • Temperature at which a substance changes from a solid to a liquid.

  13. I will be able to explain what a change in state is and describe how matter changes state. What is a change in State? • Vaporization • Process by which liquids or solids change to a gas.

  14. I will be able to explain what a change in state is and describe how matter changes state. What is a change in State? • Sublimation • Change in state from a solid directly into a gas. (skips liquid phase) • Add heat • Atoms gain energy • Escape into the air as a gas. • Example: Dry Ice

  15. I will be able to explain what a change in state is and describe how matter changes state. What is a change in State? • Evaporation • Add heat to a liquid • Atoms gain energy. • Move faster • Evaporation • Particles can escape from the surface of a liquid if enough heat is added.

  16. I will be able to explain what a change in state is and describe how matter changes state. What is a change in State? • Not in notes, write in the space in the far left box at the bottom. • Boiling • A rapid change from a liquid to a gas (vapor) • Boiling Point • The temperature at which this occurs in a liquid. • 100°C • 212°F

  17. I will be able to explain what a change in state is and describe how matter changes state. What is a change in State? • Condensation • The change in state from a gas to a liquid. • Cooling a gas • Particles lose energy.

  18. I will be able to explain what a change in state is and describe how matter changes state. What is a change in State? • Deposition • Change in state from a gas directly to a solid. • Substance cools. • Atoms lose energy • No liquid forms in the process. • Example: • Water vapor turns into ice crystals.

  19. I will be able to explain what a change in state is and describe how matter changes state. What is a change in State? • Freezing • Liquid becomes solid. • Loss of energy. • Particles slow down • Temperature cools • Freezing point • Temperature at which a substance changes into a solid. • Water = 0C or 32F

  20. I will be able to explain what a change in state is and describe how matter changes state. What happens to matter when a change of state occurs? • Mass is Conserved • The amount of matter stays the same during a phase change. • The mass does not change when its state changes. • Each state constrains the same amount of matter.

  21. I will be able to explain what a change in state is and describe how matter changes state. What happens to matter when a change of state occurs? • Mass is Conserved
