Properties of MatterMatter Anything with mass
that takes up space
2
matter can be classified into the following
categories
Matter
Anything that takes up space And has mass
Mixtures
Pure Substances

Pure Substances2 types
Elements
Compounds
-Only one kind of particle called an atom -
Cannot be broken down into simpler form -Listed
in the Periodic Table -Written as a symbol, E.g.
Oxygen O
-Two or more elements bond to form a molecule
-Can be separated using chemical means -Can be
written as a chemical formula Eg. Water H2O
5
Mixtures

• Composed of 2 or more pure substances
• Can be separated using physical means
• 2 types

Homogenous (solution)
Heterogenous (mechanical mixture)

• Only 1 visible phase
• Uniformly mixed together
• E.. Kool-Aid, tea, salt water

• Two or more visible phases
• E.g. Cereal, oil and vinegar,
• vegetable soup

Physical Properties
Description of a substance

• QUALITATIVE
• Colour
• Phase
• Hardness
• Malleability
• Ductility
• Viscosity
• Lustre
• brittleness

• QUANTITATIVE
• Melting point
• Boiling point
• Solubility
• Density
• Mass
• Volume

9
Hardness

• How difficult it is to scratch a substance

10
Malleability

• Most metals are malleable - they can be bent or
  hammered into different shapes

11
Brittleness

• Substances that are non-malleable are also called
  brittle

MICA
12
Ductility

• Ability of a material to be stretched into a wire
  without breaking

13
Solubility
Ability of a substance to dissolve in another
SOLUBLE
INSOLUBLE
14
Viscosity
How thick or hard to pour a liquid is
15
Density
Mass per unit of volume
16
Physical change
A change in which the composition of the
substance remains the same and no new substances
are produced
