Matter
  • Anything that has mass and takes up space. 
   –Mass= a measure of the amount of “stuff” the 
    object contains (this is not to be confused with 
    weight)
                                        Properties
        There are properties that are used to describe matter. 
  •   Physical Property
       – can be observed without changing the identity of the substance
           • color
           • texture
           • density
           • viscosity
           • change in state
           • solubility
           • malleability
           • mass
           • volume
           • ductility
           • luster 
           • boiling point, freezing/melting point
                                           Properties
       • Chemical Property
             - describes the ability of a substance to undergo                         changes in 
       identity
             - a new substance is produced
             * reactivity
             * toxicity
             * pH
             * conductivity
             * fermenting
             * oxidation – such as rusting or tarnishing
             * flammability
             *combustibility
                       Properties
    • Examples:
       –viscosity                physical
       –reactivity               chemical
       –density                  physical
       –solubility               physical
       –tarnishing               chemical
                     Matter’s Changes
   •   Physical Change
       – properties remain the same
       – changes the form of a substance without changing 
          its identity
       – All changes in state! (freeze, melt, condense, 
          evaporate, and sublimate)
       – Examples:
           • Boil, dissolve, break, split, crack, grind, cut, crush, and 
             bend.
