Characteristic Properties of Matter

  1. 1. Characteristic Properties of Matter
  2. 2. How Are You Identified? <ul><li>Eye Color </li></ul><ul><li>Hair Color* </li></ul><ul><li>Skin Color </li></ul><ul><li>Fingerprints </li></ul><ul><li>DNA </li></ul><ul><li>These are all characteristics you have that will stay with you for life and can be used to identify you. </li></ul><ul><li>*may change due to age or vanity </li></ul>
  3. 3. First, A Quick Review <ul><li>Matter is anything that has mass and takes up space. </li></ul><ul><li>Matter is the “stuff” (atoms and molecules) that makes up the universe </li></ul><ul><li>Matter is stuff </li></ul>
  4. 4. Examples of Stuff (aka matter) <ul><li>Plants, animals, rocks, water, soda, air, oxygen are all examples of matter </li></ul><ul><li>Matter can be living or non living </li></ul><ul><li>Matter can be solid, liquid or gas </li></ul><ul><li>They are all made of atoms and molecules </li></ul><ul><li>They all have mass and take up space </li></ul><ul><li>They are all “stuff”. Yet all of the examples of stuff listed above are different </li></ul><ul><li>They all have different characteristics or properties that can be used to identify them </li></ul><ul><li>Characteristics of matter can be either physical properties or chemical properties </li></ul>
  5. 5. Characteristic Properties of Matter <ul><li>Characteristic properties help scientists identify a particular substance </li></ul><ul><li>Characteristic properties are always the same for each kind of matter </li></ul><ul><li>Characteristic properties do not change even though the shape or amount of matter may change </li></ul><ul><li>Characteristic properties are like the eye color, hair color, skin color, fingerprints and DNA of matter </li></ul>
  6. 6. What Are Some Physical Characteristic Properties? <ul><li>Physical properties can be </li></ul><ul><ul><li>seen or measured without changing the identity of the substance </li></ul></ul><ul><ul><li>identified or described with your senses </li></ul></ul><ul><li>Melting point, boiling point, freezing point </li></ul><ul><li>State of matter at room temperature (solid, liquid or gas) </li></ul><ul><li>Density </li></ul><ul><li>Magnetic properties </li></ul><ul><li>Solubility (will it dissolve in another substance?) </li></ul><ul><li>Conductivity (will it conduct heat, electricity) </li></ul><ul><li>Ductility, malleability (can it be drawn into a wire or pounded into a thin sheet) </li></ul>
  7. 7. What Are Some Physical Characteristic Properties?
  8. 8. What Are Some Chemical Characteristic Properties? <ul><li>Chemical properties </li></ul><ul><ul><li>may not be observed with your senses. </li></ul></ul><ul><ul><li>determines how a substance interacts with another substance. </li></ul></ul><ul><ul><li>determine if the substance can change into a new substance with different properties. </li></ul></ul><ul><li>Flammability </li></ul><ul><li>Reactivity (how it behaves in the presence of another substance) </li></ul><ul><li>Oxidation (another word for rust and tarnish) </li></ul>
  9. 9. What Are Some Chemical Characteristic Properties?
  10. 10. Can You Identify? <ul><li>Physical Properties: </li></ul><ul><ul><li>Liquid at room temperature </li></ul></ul><ul><ul><li>Boiling point is 100 0 C </li></ul></ul><ul><ul><li>Color is clear </li></ul></ul><ul><ul><li>Density is 1 g/cm 3 </li></ul></ul><ul><li>That was easy! </li></ul>
  11. 11. Let’s Try Another! <ul><li>Physical Properties </li></ul><ul><ul><li>Density is 8.96 g/cm 3 </li></ul></ul><ul><ul><li>Insoluble in H 2 O </li></ul></ul><ul><ul><li>Ductile, malleable </li></ul></ul><ul><li>Chemical Properties </li></ul><ul><ul><li>Oxidizes </li></ul></ul><ul><ul><li>Reacts with acids </li></ul></ul><ul><li>Hint? </li></ul><ul><li>What do you think the flame is made of? </li></ul><ul><li>Does gold (Au) oxidize? How do you know? </li></ul>
  12. 12. Now You’re On Your Own <ul><li>?????????????????? </li></ul>
