Slide 1

The Organization of Matter

Matter

Mixtures:

a) Homogeneous (Solutions)

b) Heterogeneous

Pure Substances

Compounds

Elements

Atoms

Nucleus

Electrons

Protons

Neutrons

Quarks

Quarks

Slide 2

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.

Slide 3

Properties of Matter

Volume

Mass

Energy Content (think Calories!)

Extensive properties depend on the amount of matter that is present.

Intensive properties do not depend on the amount of matter present.

Melting point

Boiling point

Density

Slide 4

Separation of a Mixture

The constituents of the mixture retain their identity and may be separated by physical means.

Slide 5

Separation of a Mixture

The components of dyes such as ink may be separated by paper chromatography.

Slide 6

Separation of a Mixture by Distillation

Slide 7

Separation of a Compound

The Electrolysis of water

Water  Hydrogen + Oxygen

2 H2O  2 H2 + O2

Reactant  Products

Compounds must be separated by chemical means.

With the application of electricity, water can be separated into its elements
