6. “Crowdedness” M = 6g M = 4g V = 1cm3 V = 1cm3 D = D = M = 16g M = 6g

7. Which of these could be the same uniform material at the same temp and pressure?
M = 6g
V = 1cm3
D =
M = 4g
V = 1cm3
D =
M = 16g
V = 4cm3
D =
M = 6g
V = 4cm3
D =

8. What would be the density of another sample of the same uniform material that is 8cm2 ?
Draw it
M = 6g
V = 4cm3
D =

9. Degree of floating Water at 4 degrees Celsius has a density of 1g/mL
Objects with densities less than 1g/ml generally float in water.
The density is the fraction that rest below the surface
