1. Viscosity Is the resistance to flow Is an Intensive Property Example:
Syrup vs Water
Is an Intensive Property

2. Density

3. Density Ratio of mass to volume Formula D = M V
Is a physical property so we can use it to
identify substances
D = density (g/mL or g/cm3)
M = mass (g)
V = volume (mL or cm3)

4. So is Density an Intensive or Extensive Property?

5. The density of water is 1.00 g/mL.
If we half the amount of water, what will the new density be?

6. Density The heavier or larger density sinks
Which one will sink, water or oil?
Density at 20°C (g/mL)
Water
1.00
Oil
0.82
Cork
0.24
Milk
1.031

7. Density The heavier or larger density sinks
Ex: Which will float, water or cork stopper?
Density at 20°C (g/mL)
Water
1.00
Oil
0.82
Cork
0.24
Milk
1.031

8. Density The heavier or larger density sinks
Which will sink, water or milk?
Density at 20°C (g/mL)
Water
1.00
Oil
0.82
Cork
0.24
Milk
1.031

9. Density Calculations

10. D = M V

11. What is the density of an object having a mass of 8
What is the density of an object having a mass of 8.0 g and a volume of 25 cm3?
D = M = V = Formula:

12. The density of 24 carat pure gold is 19. 29 g/cm3
The density of 24 carat pure gold is g/cm3. What is the mass of a gold sample whose volume was 1.84 cm3.
D = M = V = Formula:

13. If Dawn Dish Soap has a density of 1. 06 g/mL and I mass out 50
If Dawn Dish Soap has a density of 1.06 g/mL and I mass out 50.5 g of dish soap, what will its volume be in mL?
D = M = V = Formula:
