Transcript

  • 1. How can physicalproperties be used to identify matter?
  • 2. MatterEverything around us that has: Mass and Volume Example Table, chair, board, water , juice, air, bottle, pencil case.
  • 3. Mass Is the amount ofmatter in an object.
  • 4. Tool for measuring mass.Digital Two panbalance balance
  • 5. Units for measuring mass. Gram (g)systemMetric Kilogram (Kg)
  • 6. Volum eAmount of space an object takes.
  • 7. Tool for measuring volume. (For liquids)Graduated cylinder
  • 8. Units for measuring volume. Milliliter (ml)systemMetric Liter (L)
  • 9. Mass Volum and e are calledPhysical properties (Something you can observe or measure)
  • 10. DensityDensity = Mass Volum e
  • 11. Units for measuring density. g/mlFor liquids Kg/ml g/l Kg/ml
  • 12. Units for measuring density. g/cm3For solids Kg/cm3 g/m3 Kg/m3
  • 13. Calculating density. Example 1A wooden block has a mass of 20 g. Itsvolume is 10 cm3. What is the density ofthe wooden block? MassDensit =y Volume = 2 g 0 1 cm3 0 = 2 g/cm
  • 14. Example 2A green ball has a mass of 100 g and avolume of 200 cm3. What is the density ofthe green ball? MassDensit =y Volume = 10 g 0 20 cm3 = 0 g/cm ½ 3
  • 15. Example 3A yellow ball has a mass of 50 g and avolume of 10 cm3. What is the density ofthe yellow ball? MassDensit =y Volume = 5 g 0 1 cm3 0 = 5 g/cm 3
