Density as a Concept
At what density will an object float in water?
Any density less than 1.0 g/cm cubed
D = ?
M = 150g
V = 50mL
D = 3 g/mL
What is the definition of density?
The amount of mass in an object in a given volume.
D = 2.7 g/mL
M = ?
V = 100 mL
M = 270 g
D = 2.5 g/mL
M = 50 g
V = ?
V = 20 mL
If you decrease the mass of an object but not the volume, what happens to density?
The density decreases
D = ?
M = 0.75 g
V = 0.25 mL
D = 3 g/mL
What is the definition of mass?
The amount of matter in an object.
D = 1.74 g/mL
M = ?
V = 63 mL
M = 109.62g
D = 0.85 g/mL
M = 125 g
V = ?
V = 147 mL
If you decrease the volume of an object but the mass, what happens to its density?
The density increases
D = ?
Mass = 200 g
Volume = 250 mL
D = 250 mL
What is the definition of volume?
The amount of space that an object takes up.
D = 1.25 g/mL
M = ?
V = 400 mL
M = 500 g
D = 2 g/mL
M = 64 g
V = ?
V = 32 mL
If I put a 5,000 pound an object in a swimming pool, will it sink or float?
We do not have enough information to answer
D = ?
M = 45.87 g
V = 21.42 mL
D = 2.14 g/mL
What kind of property is density?
A physical property
D = 0.003 g/mL
M = ?
V = 1500 mL
M = 4.5 g
D = 0.8 g/mL
M = 500 g
V = ?
V = 625 mL
Will the following object float or sink?
Mass = 25g
Volume = 22mL
It will sink
D = ?
M = 3.6 g
V = 1200 mL
D = 0.003 g/mL
What is the unit for density?
D = 0.95 g/mL
M = ?
V = 250 mL
M = 237.5 g
D = 0.18 g/mL
M = 18 g
V = ?
V = 20 mL
