									       Properties of Matter
 What is matter?
 What are the many kinds of properties of
            Matter is
Anything that has mass and takes up space.

 Mass is the amount of stuff
 something is made of.
  Mass is measured in grams using
  a balance.

 Volume is the amount of space
 something takes up.
  Volume is measured in liters using
   a graduated cylinder.
          Properties of Matter

 Physical   properties are characteristics or
 traits of the matter being described.
  o   Basically, these are descriptions and
      behaviors observed.
  o   The matter remains the same; it does not
      change into something else.
 Chemical properties are behaviors that
 matter does that will change it into another
 kind of matter.
              Physical Properties
Senses are used to describe matter.
      Seeing
           Color (ranges from colorless to a color)
           Clearness or clarity (ranges from transparent to opaque).
           Size (dimensions of matter)
           Shape (round, square, rectangular, or irregular)
           Luster (shiny to dull)
      Smelling (ranges from odorless to an odor).
      Hearing (ranges from no sound –to a specific sound.
      Touching
           Texture (smooth or rough)
           Temperature (cold to hot)
           Hardness (hard to soft)
          Physical Properties
        Size, Shape, and Color


Colorless—has no color
            Clearness or Clarity
3 terms can describe a ―things‖ degree of clearness:
      Transparent
           Easily seen through
           Like looking through a window
           Objects on the other side of the material look
            exactly as they do if the material were not there.

      Translucent
           Light can pass through
           Objects cannot be seen
           Like looking through stained glass or frosted glass.

      Opaque
           No light can pass through
           Like looking at a wall and seeing nothing that is on the other side.

      circular, window that is
                                                stained glass
      translucent—you can see light            "almost" clear plastic
      through the window, but you                lids
      cannot read the words.

   Some shiny things
    have a metallic luster

Freezing/Melting and Boiling Points
  Matter can change its state: Solid, Liquid, or
  Adding or taking away heat changes the
   state of matter.
        Ice can gain heat to change into water--Melting

        Liquid water can cool to become ice--Freezing

        Water can heat up to form water vapor--Boiling
        Physical Properties
Freezing/Melting and Boiling Points
 Each  form of matter has its own
  temperatures to boil and to melt and
 The melting and freezing temperatures are
  the same because these are opposite
 In science, the Celsius scale is used to
  note temperatures.

   The melting point is the
    temperature at which a solid
    melts into a liquid.
                                    Freezing Point
   The freezing point is the
    temperature at which a liquid
    changes into a solid.

   The boiling point is the
    temperature at which a liquid
    becomes a gas.
Boiling and Melting/Freezing Points

   The melting/freezing point
    of water is 0 oC

          Physical Properties
 Density describes the
  relationship of mass to
  volume or, in other
  words, how heavy
  something is compared
  to its size.
 Things that are very
  dense usually sink;
  whereas, things that are
  not dense, float.
            Determining Density
    Density is found by:
    1.   Knowing the mass and volume of an object.
    2.   Dividing the mass by the volume. D = m/v

         Object A has a mass of 10.0 g
                      a volume of 5.0 ml

              Divide 10.0 g by 5.0 ml  D = 10.0/5.0
                     Density= 2.0 g/ml
            Floating or Sinking
    Water’s density is 1.0 g/ml

    If the density of an object is greater than
    1.0 g/ml, the object will sink.

    If the density of an object is less than
     1.0 g/ml, the object will float.
          Physical Properties
To determine density:
     Mass the item
     Find the item’s volume
     Divide the mass by the volume

    Density = Mass divided by Volume

                 D = M/V
           Physical Properties
   If both have the same size, which will be
    more dense?
