Physical properties like mass and volume can be used to identify matter. Mass is measured using a balance and volume is measured using a graduated cylinder. Density, which is the ratio of mass to volume, can also be used and is calculated by dividing the mass by the volume. Common units for measuring these properties include grams, kilograms, milliliters, liters and cubic centimeters. Other physical properties include color, shape, texture, state, and abilities to transfer heat and conduct electricity.
How can physical properties be used to identify matter
- 1. How can physical properties be used to identify matter?
- 2. Matter Everything around us that has: Mass and Volume Example Table, chair, board, water , juice, air, bottle, pencil case.
- 3. Mass Is the amount of matter in an object.
- 4. Tool for measuring mass. Digital Two pan balance balance
- 5. Units for measuring mass. Gram (g) system Metric Kilogram (Kg)
- 6. Volum e Amount of space an object takes.
- 7. Tool for measuring volume. (For liquids) Graduated cylinder
- 8. Units for measuring volume. Milliliter (ml) system Metric Liter (L)
- 9. Mass Volum and e are called Physical properties (Something you can observe or measure)
- 10. Density Density = Mass Volum e
- 11. Units for measuring density. g/ml For liquids Kg/ml g/l Kg/ml
- 12. Units for measuring density. g/cm3 For solids Kg/cm3 g/m3 Kg/m3
- 13. Calculating density. Example 1 A wooden block has a mass of 20 g. Its volume is 10 cm3. What is the density of the wooden block? Mass Densit = y Volume = 2 g 0 1 cm3 0 = 2 g/cm
- 14. Example 2 A green ball has a mass of 100 g and a volume of 200 cm3. What is the density of the green ball? Mass Densit = y Volume = 10 g 0 20 cm3 = 0 g/cm ½ 3
- 15. Example 3 A yellow ball has a mass of 50 g and a volume of 10 cm3. What is the density of the yellow ball? Mass Densit = y Volume = 5 g 0 1 cm3 0 = 5 g/cm 3
- 16. Other physical Color properties Shape Textur e State Ability to transfer heat Ability to conduct electricity
