Density

  1. 1. Density
  2. 2. <ul><li>Density- the measure of how much mass is contained in a given unit of volume. </li></ul><ul><li> Abbrev. Ending Unit </li></ul><ul><li>Density D g/cm 3 </li></ul><ul><li>Mass m g </li></ul><ul><li>Volume V cm </li></ul>
  3. 3. Density Column-Think about it??? List the following in order of density (from the heaviest to the lightest). Water, Dawn Dish Soap, Vegetable Oil, Rubbing Alcohol, Karo Syrup, Honey and Lamp Oil
  4. 4. 1.42 Honey 1.33 Light Corn Syrup 1.06 Dawn Dish Soap 1.00 Water .92 Vegetable Oil .80 Lamp Oil .79 Rubbing Alcohol Density Material
  5. 5. Density Column What order of density for the following: Water, Dawn Dish Soap, Vegetable Oil, Rubbing Alcohol, Karo Syrup, Honey and Lamp Oil
  6. 6. <ul><li>To find density of an object, you need the mass and volume of the object. </li></ul><ul><li>1. Mass- remember to use the balance. </li></ul><ul><li>2. Volume- there are 2 ways to find the volume of objects. </li></ul>
  7. 7. <ul><ul><ul><li>a. To find the volume of a circular object use a graduated cylinder. </li></ul></ul></ul><ul><ul><ul><li>-Measure some water in a graduated cylinder </li></ul></ul></ul><ul><ul><ul><li>-Drop the object and reread the graduated cylinder </li></ul></ul></ul><ul><ul><ul><li>Subtract the two numbers....you should always have a positive number. </li></ul></ul></ul>
  8. 8. 200 mL 260 mL Water Water with Coin Calculate the volume of the coin. 260 mL – 200 mL = 60 mL 60 mL = 60 cm3
  9. 9. <ul><ul><li>b. To find the volume of a rectangular object use a ruler. </li></ul></ul><ul><ul><li>Volume = Length X Width X Height cm 3 cm x cm x cm </li></ul></ul>2 cm 1 cm 2 cm 2 cm X 1 cm x 2 cm = 4 cm 3
  10. 10. <ul><li>What is the volume of the box?? </li></ul>5 cm 2 cm 3 cm 5 cm X 2 cm X 3 cm = 30 cm 3
  11. 11. : : X D m V D = m / v m = D x v v = m / D
  12. 12. <ul><li>Ex: m = 2 g </li></ul><ul><ul><ul><ul><li>v = 1 cm 3 </li></ul></ul></ul></ul><ul><ul><ul><ul><li>D = 2 g/ cm 3 </li></ul></ul></ul></ul><ul><li>Ex: m = 6 g </li></ul><ul><ul><ul><ul><li>v = 3 cm 3 </li></ul></ul></ul></ul><ul><ul><ul><ul><li>D = 2 g/ cm 3 </li></ul></ul></ul></ul>D = m / v v = m / D
  13. 13. <ul><li>Ex: m = </li></ul><ul><ul><ul><ul><li>v = 1cm X 2cm X 4cm </li></ul></ul></ul></ul><ul><ul><ul><ul><li>D = 2 g/cm 3 </li></ul></ul></ul></ul><ul><ul><ul><ul><li>m = 16 g </li></ul></ul></ul></ul><ul><ul><ul><ul><li>v = 8 cm 3 </li></ul></ul></ul></ul><ul><ul><ul><ul><li>D = 2 g/cm 3 </li></ul></ul></ul></ul>m = D x v
