  1. States (Phases) of Matter Plasma Hill Science 6

  2. Matter Can Exist in Four Phases: • 1. Solid • 2. Liquid • 3. Gas • 4. Plasma

  3. Solids Have a definite shape Have a definite volume Tiny particles that make up a solid are packed very closely together Particles are able to vibrate! A solid is able to keep its definite shape.

  4. Liquids A. Have no definite shape. B. Have a definite volume. C. Particles are free to move; not packed as tightly as a solid. D. Take the shape of a container. *What do you think would happen if you tried to pour one liter of water into a half-liter bottle? (The water will overflow)

  5. Liquids Viscosity: The resistance of a liquid to flow. • Honey has a high viscosity compared to water. • Honey flows more slowly than water. • Automobile oil has a high viscosity.

  6. Review • Solids • Have a definite ________________________ • Have a definite ________________________ • Particles are _____________ closely together, but can _____________________. • Liquids • Have a no definite _____________ (take the ______________ of container) • Have a definite ________________________ • Particles are ____________________, but can _____________around one another.

  7. Gases Have no definite shape. Have no definite volume. Fills all available space in a container. • Particles tend to spread far out from one another, but they can be pushed close together such as in… -Pumping air into a bicycle tire. -Blowing up a balloon.

  8. Gases If allowed, gases will expand without limit. Gases would expand into space, but what keeps them surrounding the Earth? Gravity!

  9. Solids, Liquids, and Gases

  10. Plasma • Rare on Earth, but one of the most common phases found in the universe. • High in energy, so very dangerous to living things. • Stars, lightning, fluorescent lights

  11. Plasma • The negatively charged electrons (yellow) are freely streaming through the positively charged ions (blue). • Where electrons have come loose from their atoms or molecules because they have taken in so much energy.

  12. Review, too! • Gases • Have a no definite _________, take _________ of container. • Have a no definite _________, spread out to fill container. • Particles spread out and _____________ quickly around one another. • Plasma • So much energy that _______________ separate from nucleus of atom and move freely within the substance. • Examples: __________________________________________
