Chapter 9
  • Classification of
  • Matter

3
Physical Property
  • Any characteristic of a material that you can
    observe without changing the substances that make
    up the material.

4
Physical Properties
  • Color
  • Shape
  • Size
  • Density
  • Melting Point
  • Boiling Point

5
Chemical Property
  • Characteristic of a substance that indicates
    whether it can undergo a certain chemical change.

6
Chemical Properties
  • Flammable
  • Combustible
  • Reactive
  • (Acidic)
  • (Basic)

7
Physical Change
  • A change in the size, shape, or state of matter
    of a substance.
  • (The substances in a material DO NOT change.)

8
Examples of physical changes
  • ?
  • ?
  • ?
  • ?
  • ?
  • ?

9
Chemical Change
  • Change of one substance in a material into a new
    substance.
  • (A new substance is produced.)

10
Law of Conservation of Mass
  • The mass of all Substances present before a
    chemical change equals the mass of the substances
    remaining after a chemical change.

11
L of C of M(cont.)
  • During a chemical change, matter is neither
    created nor destroyed.

12
Matter is divided into what two categories?

13
Substance or Mixture

14
Substance
  • A substance is Pure made up of one thing.

15
Elements
  • Made up of only one type of atom.

16
Compounds
  • Made up of two or more different types of atoms.
  • Combined in specific ratios.
  • H20 2 H 1 0

17
Mixtures
  • Two or more substances with no definite ratio.
  • Can be separate by physical means.

18
Homogeneous
  • Homo- prefix that means same
  • A mixture where all materials looks the same and
    individual parts cannot be seen even with a
    microscope
  • Another name for this type of mixture is...

19
Solution
  • -Particles to small to see
  • - Uniformly spread out
  • - Never settle

20
Heterogeneous
  • Hetero- prefix that means different
  • A mixture where materials are larger and can
    either be seen with a microscope or with the
    naked eye
  • There are two types of this kind of mixture...

21
Colloid
  • - Never settles
  • -Scatters light (Tyndal Effect)

22
Suspension
  • - Visible particles
  • - Particles will settle
