1 The Organization of Matter Matter Matter Mixtures: a) Homogeneous (Solutions) b) Heterogeneous Pure Substances Compounds Elements Elements Atoms NucleusElectrons ProtonsNeutrons Quarks Quarks

2 Phase Differences Solid Solid – definite volume and shape; particles packed in fixed positions. Liquid Liquid – definite volume but indefinite shape; particles close together but not in fixed positions Gas Gas – neither definite volume nor definite shape; particles are at great distances from one another Plasma Plasma – high temperature, ionized phase of matter as found on the sun.

3 Properties of Matter Volume Mass Energy Content (think Calories!) Extensive properties Extensive properties depend on the amount of matter that is present. Intensive properties Intensive properties do not depend on the amount of matter present. Melting point Boiling point Density

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

5 Separation of a Mixture The components of dyes such as ink may be separated by paper chromatography.

6 Separation of a Mixture by Distillation

7 Separation of a Compound Separation of a Compound The Electrolysis of water Water  Hydrogen + Oxygen 2 H 2 O  2 H 2 + O 2 Reactant  Products chemical Compounds must be separated by chemical means. With the application of electricity, water can be separated into its elements
