Transcript

  • 1. The 3 states of matter 8th grade Made by: Lance Bengochea
  • 2. The 3 States of Matter O State of Matter- the physical forms in which a substance exists. O There are 3 states of matter. O Solids O Liquids O Gases
  • 3. A. Solids O Solid- the state of matter that has a definite shape & volume. O A solids shape and volume stay the same.
  • 4. Solids (cont.) O Particles are very close together. O They have a strong attraction for each other. O The particles vibrate.
  • 5. Examples of Solids O Wood O Humans O Computers O Marbles O Weights
  • 6. B. Liquids O Liquid- the state of matter that has a definite volume, but takes on the shape of its container. O Particles move fast enough to overcome the attraction between some of the particles. O Particles slide past each other. O Liquids easily change shape. O Liquids don’t easily change volume.
  • 7. Liquids (cont.) O Ex: if you have a glass of milk how can you change the shape? How can you change the milks volume? O All liquids have surface tension. O Surface tension- a force that holds the particles together. O Surface tension (ST) causes some liquids to form spherical drops.
  • 8. Liquids (cont.) O Different liquids have different ST. O Ex: gasoline, has low ST and forms flat drops. O All liquids have viscosity.
  • 9. 1. Viscosity O Viscosity- a liquids resistance to flow Low viscosity High viscosity
  • 10. Examples of Liquids O Water O Apple juice O Soda O Kool-aid O Milk
  • 11. C. Gases O Gas- the state of matter that has no shape or volume. O One small helium tank can fill almost 700 balloons. O How is this possible? O The tank is under pressure.
  • 12. Gases (cont.) O Particles in a gas move quickly, so they can break away from their attraction for other particles. O The amount of empty space between gas particles can change.
  • 13. Example Helium tank Helium balloon A helium tank holds more gas particles and they are closer together, but in a balloon they are much farther apart and they have much more room to move around
  • 14. Examples of Gases O Carbon Dioxide O Oxygen O Water Vapor O Hydrogen O Helium
  • 15. Examples O These are the particles of each of the states of matter below.
