The Organization of Matter
Matter
Mixtures:
a) Homogeneous (Solutions)
b) Heterogeneous
Pure Substances
Elements
Compounds
Atoms
Nucleus
Protons
Quarks
Electrons
Neutrons
Quarks
Phase
Differences
Solid – definite volume and shape; particles packed
in fixed positions.
Liquid – definite volume but indefinite shape;
particles close together but not in fixed positions
Gas – neither definite volume nor definite shape;
particles are at great distances from one another
Plasma – high temperature, ionized phase of matter
as found on the sun.
Properties of Matter
Extensive properties depend on the amount
of matter that is present.
Volume
Mass
Energy Content (think Calories!)
Intensive properties do not depend on the
amount of matter present.
Melting point
Boiling point
Density
Separation of a Mixture
The constituents of the mixture retain
their identity and may be separated
by physical means.
Separation of a Mixture
The components of
dyes such as ink
may be separated
by paper
chromatography.
Separation of a
Mixture by Distillation
Separation of a Compound
The Electrolysis of water
Compounds must be
separated by
chemical means.
With the application
of electricity, water
can be separated
into its elements
