									Properties of Matter

  What is matter?
  What are the many kinds of properties
   of matter?
What is Matter:
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
Examples of Clarity
   Transparent                               plastic wrap
                                               clear glass
     You are looking through a circular,
     window that is transparent—you
                                               "bubble" packing material
     can read these works through the          laminating material
     window.                                   clear plastic lids

                                            tissue paper
   Translucent                              waxed paper
     You are looking through a
     circular, window that is                paper towel
     translucent—you can see light           stained glass
     through the window, but you
                                            "almost" clear plastic
     cannot read the words.

   Opaque                                    construction paper
    You are looking through a circular,        cardboard
    window that is opaque—you                  styrofoam trays
    cannot read these works through            colored plastic lids
    the window.

 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
 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 changes.
 In science, the Celsius scale is used to
  note temperatures.
     The Melting/Freezing Point and
     the Boiling Point of Water
                                              Melting Point
   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.
Water: Boiling and
Melting/Freezing Points

   The melting/freezing
    point of water is 0 oC

   The boiling point of water
     100 o C
Physical Properties:
 Density   refers to
  how heavy
  something is
  compared to its
 Lighter things will
  float; heavier things
  will sink.
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:
   both have the same size, which will be
 If
  more dense?

    or sink?
