Density
If steel is more dense than lake water, why can a boat float?
The average density of the boat, including the steel and air, is less dense than 1.00 g/cm³.
There are liquids of different densities together in a container. What will happen to the liquid with the lowest density?
It will move to the top.
Which ranks the objects from most to least dense?
X, Z, Y, W
If two items are equal in size, the denser one will
be heavier
is the amount of mass in a given volume.
density
This chart shows the volumes of four different objects. If the objects all have the same mass, which object is the most dense?
object 3
In what order would the liquids would arrange themselves, from top to bottom?
purple, green, water, red, blue
Mason notices that his boat sinks lower into the water in a freshwater lake than in the ocean. What could explain this?
salt water is more dense than freshwater
If the density and volume of an object is known, what can also be found?
the mass of the object
Density is calculated by solving for mass divided by
volume
Cubes are three-dimensional square shapes that have equal sides. What is the density of a cube that has a mass of 12.6 g and a measured side length of 4.1 cm? (Density: D = )
.1828g/cm3
The density of gold is 19.3 g/cm3. What is the volume of a 13 g gold nugget? (Density: D = )
.67 cm3
If the objects all have the same mass, which object is the most dense?
1.079kg/m3
What is the density of a 36 g object with a volume of 15 cm3? (Density: D = )
2.4 g/cm3
The density of an object is .835 g/cm3. If its volume is 34 cm3, what is the mass of the object? (Density: D = )
28.39 g
Janice has just measured the density of an object. Which value is possible? (Density: D = )
6 g/cm^3
Which object will sink in freshwater, which has a density of 1.0 g/cm3?
Object 2, which has a density of 1.9 g/cm3
What happens when an object has a density greater than that of the surrounding liquid?
The object will sink.
Gerald is fishing. He uses a bobber that floats on the surface to show him if the line is being moved, and a lure that sits below the surface to attract fish. Which statement accurately describes the densities of these two items?
The bobber is less dense than the water, and the lure is more dense than the water.
