1
Based on its density, select the materials that will FLOAT on water
Butter: d = 1.04g/mL
Ping pong ball: d = 0.084g/cm3
Olive oil: d = 0.93g/mL
Mulch: d = 1.2g/cm3
2
How much space something occupies is . . .
volume
density
air pressure
matter
3
What are fluids, or things that are free to flow?
areas of high pressure
layers of density
musical instruments
gasses and liquids
4
5mL of ethanol weighs 3.9g and 5mL of benzene has a mass of 44g. Which liquid is denser?
Benzene
Ethanol
5
What is density?
how much something weighs
relationship between ounces and milliliters
ratio between between the mass & volume of any given sample
how dense something is
6
In which layer of the Earth is the ozone layer found?
troposphere
mesosphere
exosphere
stratosphere
7
What happens to the air as you travel higher into the atmosphere?
the air disappears
the air becomes less dense
the air gets heavier
8
How can the density of a substance be found?
multiply its mass by its volume
divide its mass by its weight
divide its volume by its mass
divide its mass by its volume
9
The layer of the Earth that scientists know very little about is the
exosphere
mesosphere
idontknowsphere
thermosphere
10
What is the density of water?
1g/mL
1.2g/mL
Water has no density
3.4g/mL
11
Mass is measured in
weight
grams
milliliters
cm3
12
What is the relationship between layering and density?
As density increases, layers become lighter
They are married
The mass is greater in the top layers
As you go from top to bottom, layers increase in density
13
A 10.0cm
3
sample of copper has a mass of 89.6g. What is the density of copper?
8.96g/mL
0.896g/cm3
89.6g/cm3
8.96g/cm3
14
Kinetic energy is defined as:
energy of motion
millibars
high pressure
quick movements
15
What is the formula for calculating density?
d = volume ÷ mass
d = mass × volume
d = mass ÷ volume
d = how heavy something is
16
A solid takes up 2.5cm
3
of space and weighs 50g. Find its density (round to nearest hundredth).
20g/cm3
2.0g/cm
0.20g/cm3
2.0g/cm3
17
True or False: All matter has density, including all solids, liquids, and gases.
True
False
18
Find the density of a gas that occupies a volume of 100mL and weighs 0.196g
0.00196g
0.00196g/mL
1.96g/mL
19
Which one of our four (4) liquid solutions was the MOST dense?
Blue
Red
Yellow
Green
20
The exosphere is the layer of the Earth that is
farthest from Earth's surface
closest to Earth's surface
the warmest layer
21
How can we determine mass?
finding a materials weight
finding a materials volume
finding the number of grams
22
An isobar indicates where air pressure is
highest
fastest
strongest
the same
23
Air particles flow from areas of
low pressure to high pressure
high pressure to medium pressure
medium pressure to low pressure
high pressure to low pressure
24

13.8g/cm3
2.34g/mL
1.38g/mL
0.38g/mL
25
Sample 1 is 45mL and weighs 54g. Sample 2 is 120mL and weighs 132g. Which sample is more dense?
Sample 2
Sample 1
26
In which layer of the Earth does weather occur?
troposphere
weatherphere
mesosphere
atmosphere
27
What is the name of the layer of air that surrounds Earth?
mesosphere
stratosphere
spearmint
atmosphere
28
When isobars are close together, this means that the wind is
slow
weak
strong
tired
29

False
True
30
True or False: Water is more dense than air.
True
False
31
If 2 liquids have equal volume but differ in mass, the liquid with the greater mass is
less dense
smaller
more dense
larger
32
The amount of stuff in something is its . . .
mass
air pressure
volume
