    • Properties of Matter
    • Properties of Matter
      Physical Properties
      Has 2 properties.
      - Physical
      -Chemical
      • Mass
      • Weight
      • Volume
      • Density
      • Malleability
      • Conductivity
      • Boiling Point
    • Mass vs. Weight
      Mass & Weight are NOT the same
      • Mass ALWAYS stays the same
      • Weight changes depending where you are.
      • Ex. On the moon your mass would be the same as on earth but your weight would be different.
    • Volume
      Malleability
      Conductivity
      Boiling Point
      Space something takes up.
      All 3 dimensional objects have it
      How easily something can be shaped
      Can carry an electric current
      At what point a
      Substance boils
    • Physical Changes to Matter
      Condensation
      Sublimation
      Is a change in size, shape, or state of matter.
      • Examples:
      • Water freezing into Ice
      • Water boiling and becoming a gas
      • Ice melting
      Where a gas is reduced to a liquid or solid form. Ex: Soda Can
      Where an object changes from a solid to a gas without becoming a liquid
    • Chemical Properties
      Chemical Changes
      Is a characteristic of a substance that indicates whether it can go through a chemical change
      • Flammability
      • Reactivity
      • pH (Acid or Base)
      • Burns
      • Produces a gas (bubbles)
      • Color change
      • Produces a precipitate (makes a solid from mixing 2 liquids)
    • Chemical or Physical Change?
      Tearing Paper?
      Mixing Salt and Water?
      Burning Paper?
      Evaporating the water to leave the salt?
      Baking Soda and Vinegar?
      Dry Ice becoming a Gas?
      Mentos and diet coke?
      Gasoline Combustion in a car?
    • Change the Cookie
      Using ONLY yourself. What are 3 ways you can physically change the cookie?
      Using ONLY yourself. What is 1 way you can chemically change the cookie?
