  14. 14. SYLLABUS<br />
  15. 15. CHEMISTRY<br />The Study of the Nature of Matter and Change<br />Matter – anything that has mass and takes up volume<br /> Examples of non-matter things? <br />Change refers to a change in properties – characteristics - of a substance. <br />
  16. 16. Physical Properties<br /><ul><li>Properties of a substance that depend on the nature of the substance itself.
  17. 17. Color
  18. 18. Melting point
  19. 19. Electrical conductivity
  20. 20. Density
  21. 21. Physical Change occurs when a substance changes its physical form: solid -> liquid. </li></li></ul><li>Chemical Properties<br /><ul><li>Properties that a substance shows as it reacts with another substance – acidic, basic, oxidant, etc.
  22. 22. A chemical change, a chemical reaction, converts one substance into one or more other substances.</li></li></ul><li>Extensive and Intensive Properties<br />Extensive Properties – depend on the amount of a substance<br />Mass<br />Volume<br />Intensive Properties – independent of the amount<br />Color<br />Melting Point<br />Density<br />
  23. 23. Classifications of Matter<br />Substance – Chemically the same throughout<br />Element – Cannot be broken down into simpler substances by chemical means<br />Compound – Chemical combination of two or more elements. All portions contain the same elements in the same proportions<br />Mixtures – Can be separated into two or more substances by physical means<br />Heterogeneous mixture – non-uniform mixture<br />Homogeneous mixture – uniform mixture<br />
  24. 24. Three States of Matter <br />Solid – has a fixed shape<br />Liquid – takes on the shape of the container, but fills the container only to the volume of the liquid; a liquid/gas interface will be formed. <br />Gas – takes on the shape of the container, and fills the container completely. <br />
  25. 25.
  26. 26. Energy<br /><ul><li>An understanding of energy is critical to the understanding of chemistry
  27. 27. Two kinds of energy
  28. 28. Kinetic energy – the energy of motion – ½ mv2
  29. 29. Potential energy - energy that depends on position
  30. 30. All systems want to get to a “place” of lower energy or greater stability - the lower energy state</li></li></ul><li>Energy (2)<br /><ul><li>In chemical changes:</li></ul>ENERGY IS CONSERVED<br /><ul><li>Energy is neither created or destroyed as a result of a chemical or physical change. </li></li></ul><li>Questions and Exercises<br />1.8, 1.10, 1.11, 1.16, 1.27, 1.28, 1.30, 1.40<br />
