1The Organization of Matter Mixtures:a) Homogeneous (Solutions)b) HeterogeneousPure SubstancesElementsCompoundsAtomsNucleusElectronsProtonsNeutronsQuarksQuarks
2Phase DifferencesSolid – definite volume and shape; particles packed in fixed positions.Liquid – definite volume but indefinite shape; particles close together but not in fixed positionsGas – neither definite volume nor definite shape; particles are at great distances from one anotherPlasma – high temperature, ionized phase of matter as found on the sun.
3Properties of MatterExtensive properties depend on the amount of matter that is present.VolumeMassEnergy Content (think Calories!)Intensive properties do not depend on the amount of matter present.Melting pointBoiling pointDensity
4Separation of a Mixture The constituents of the mixture retain their identity and may be separated by physical means.
5Separation of a Mixture The components of dyes such as ink may be separated by paper chromatography.
7Separation 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 elementsReactant ProductsWater Hydrogen + Oxygen2 H2O H O2
