### How can physical properties be used to identify matter

1. 1. How can physicalproperties be used to identify matter?
2. 2. MatterEverything around us that has: Mass and Volume Example Table, chair, board, water , juice, air, bottle, pencil case.
3. 3. Mass Is the amount ofmatter in an object.
4. 4. Tool for measuring mass.Digital Two panbalance balance
5. 5. Units for measuring mass. Gram (g)systemMetric Kilogram (Kg)
6. 6. Volum eAmount of space an object takes.
7. 7. Tool for measuring volume. (For liquids)Graduated cylinder
8. 8. Units for measuring volume. Milliliter (ml)systemMetric Liter (L)
9. 9. Mass Volum and e are calledPhysical properties (Something you can observe or measure)
10. 10. DensityDensity = Mass Volum e
11. 11. Units for measuring density. g/mlFor liquids Kg/ml g/l Kg/ml
12. 12. Units for measuring density. g/cm3For solids Kg/cm3 g/m3 Kg/m3
13. 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. 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. 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
