  1. 1. Characteristics of Matter
  2. 2. Characteristics of Matter <ul><li>Physical/ Chemical Properties </li></ul><ul><li>Mixtures/ Pure Substances </li></ul><ul><ul><li>Group Characteristics of elements from Periodic Table </li></ul></ul><ul><li>Forms of Matter </li></ul><ul><ul><li>Characteristics of solids, liquids, gases, plasmas </li></ul></ul>
  3. 3. Physical properties <ul><li>Properties that do not change the chemical nature of matter </li></ul><ul><li>Examples: </li></ul><ul><ul><li>melting point </li></ul></ul><ul><ul><li>Color </li></ul></ul><ul><ul><li>density </li></ul></ul><ul><ul><li>boiling point </li></ul></ul><ul><ul><li>odor </li></ul></ul><ul><ul><li>hardness </li></ul></ul><ul><ul><li>freezing point, </li></ul></ul><ul><li>Note that measuring each of these properties will not alter the basic nature of the substance. </li></ul>
  4. 4. Chemical properties <ul><li>Properties that change the chemical nature of matter </li></ul><ul><li>Characteristics which are exhibited as one substance is chemically transformed into another </li></ul><ul><li>Example </li></ul><ul><ul><li>Iron rusting. When iron (an element, symbol = Fe) rusts, it combines with oxygen to form a reddish-colored compound called ferric oxide (formula = Fe2O3) </li></ul></ul>
  5. 5. Mixtures and Pure Substances <ul><li>All matter can be separated into two categories by asking the question &quot;Is only one chemical substance present in the sample being considered?&quot; </li></ul><ul><ul><li>YES - Pure Substance </li></ul></ul><ul><ul><li>NO - Mixture </li></ul></ul><ul><li>A mixture is one in which two or more pure substances retain their chemical identity. </li></ul><ul><ul><li>For example, if you dissolve some sugar into water, the sugar molecules and water molecules remain as sugar and water </li></ul></ul><ul><li>All pure substances can be separated into two categories by asking the question &quot;Can the sample be further decomposed by chemical means?&quot; </li></ul><ul><ul><li>YES - Compound </li></ul></ul><ul><ul><li>NO - Element </li></ul></ul>
  6. 8. Sample Questions <ul><li>How does mold form and how can you stop it? </li></ul><ul><li>How and why does rust form? </li></ul><ul><li>Why won’t oil and water mix? </li></ul>
