1 The Organization of Matter Mixtures:a) Homogeneous (Solutions)b) HeterogeneousPure SubstancesElementsCompoundsAtomsNucleusElectronsProtonsNeutronsQuarksQuarks
2 Phase 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.
3 Properties 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
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.
7 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 elementsReactant ProductsWater Hydrogen + Oxygen2 H2O H O2
