Properties of Matter
3
Matter
  • Matter is anything that has mass and volume.
  • (Mass is a measure of the quantity of something
    and volume is how much space it takes up)

4
PHYSICAL PROPERTIES OF MATTER
  • A Physical Property of a substance is a
    characteristic or description of the substance
    that may help to identify it.
  • For example Sodium is a silvery metal.

5
Physical Properties Observed with the Senses
  • Colour
  • Texture
  • Odour
  • Lustre
  • Clarity
  • Taste

6
The States of Matter
  • Solid, Liquid, Gas, (Plasmas)

Solar plasmas of Jupiter
7
2. Hardness
  • Resistance of a solid to being scratched or
    dented
  • Example diamond is harder than glass

Glass tiles are cut using water and diamond
encrusted blades
8
3. Malleability
  • Ability of a metal to be hammered or bent into
    different shapes
  • Example Aluminum foil is easily bent

Chromium metal bent into different shapes
9
4. Ductility
  • Ability of a metal to be pulled into wires
  • Example Copper is very ductile and is commonly
    used for electrical wiring

10
5. Melting and Boiling Points
  • Temperature at which substances change state
  • Water changes from solid to a liquid at 0ºC

11
6. Crystal Form
  • The solid form taken by many minerals. Each
    mineral usually takes a characteristic pattern
  • Salt Crystals usually look like tiny cubes

12
7. Solubility
  • The ability of a substance to dissolve in a
    solvent
  • Example Sugar is soluble in water

13
8. Viscosity
  • How easy a liquid flows
  • Example The thicker the liquid, the slower it
    flows and is more viscous. Corn syrup is viscous

14
9. Density
  • The amount of matter per unit volume
  • Density mass/volume
  • Example Lead is very dense, feathers are not
    dense

15
10. Conductivity
  • If a substance is able to conduct heat or
    electricity.
  • Conductor able to conduct
  • Example most metals, copper is very good
  • Insulator has little or no conductivity
  • Example styrofoam, glass

16
CHEMICAL PROPERTIES OF MATTER
  • A Chemical Property of a substance describes the
    behaviour of a substance as it becomes a new
    substance

17
1. Combustibility
  • The ability of a substance to react with oxygen
    to produce carbon dioxide, water and energy
  • Gasoline is very combustible or flammable. Water
    is nonflammable.

18
2. Reaction with Acid
  • The ability of a substance to react with acids to
    produce a gas
  • Example Zinc reacts with acid to produce
    bubbles of gas.

19
Other Examples include
  • Absorbs heat during reaction
  • Forms gas when heated
  • Reacts with water
  • Emits heat during reaction
  • Emits light during reaction
  • Forms a precipitate (solid) in a solution

MATTER
- has mass and takes up space, made up of atoms
and molecules
Pure Substances
Mixtures
Homogeneous Mixtures
Heterogeneous Mixtures
Solutions
Elements
Compounds
  • looks like one
  • substance
  • -Homogeneous
  • E.g. ______
  • simplest form
  • cannot be broken
  • down
  • - E.g. ________
  • made of 2 or more
  • elements
  • can be broken
  • down chemically
  • - E.g. ________

- Mechanical Mixtures - individual substances
are visible - E.g. ____________
- Suspensions - tiny particles of one substance
are held within Another -E.g. __________
