Standard I Matter Objective 2d
Mass & volume to density
1. You have two rocks, granite and marble.
Granite is bigger but has the same mass as
marble. How will the density of the two rocks
compare?
A. the density of marble is greater because
its volume is greater
B. the density of marble is greater because
its volume is less
C. the density of marble is less because
its volume is greater
D. the density of marble is less because
its volume is less
2. Would pumice (an igneous rock that floats in water) have a higher or lower or the same
density as obsidian (an igneous rocks that sinks in water)?
A. higher
B. lower
C. same
D. neither
3. What does water do when it freezes?
A. water becomes less dense when it freezes
B. water becomes more dense when it freezes
C. water turns from a solid to a liquid when it freezes
D. water has the same density as a liquid and as a solid
4. What would happen to the density of an object if you decreased the mass?
A. density would increase
B. density wouldn’t change
C. density would decrease
D. density would be the same
5. What would happen to the density of an object if you decreased the volume?
A. density would increase
B. density wouldn’t change
C. density would decrease
D. density would be the same
6. How could you get a piece of steel to float?
A. increase its mass
B. increase its volume
C. nothing, steel can never float
D. nothing, steel always floats on its own
7. A golden-colored cube is handed to you. The person wants you to buy it and tells you it is a
gold nugget. You pull out your science book and read that gold has a density of 19.3 g/cm3. You
measure the cube and find it has 2 cm on each side, and has a mass of 40 g. Should you buy it
because it is gold?
A. Yes, it is gold and is a great deal
B. No, it is not gold because it is more dense than gold is
C. No, it is not gold because it is less dense than gold is
D. Yes, it looks like gold so it must be gold
8. A bowling ball is small in size, but is very heavy. A beach ball is larger in size, but is not very
heavy. Which is more dense?
A. beach ball
B. bowling ball
C. both are the same density
D. you can’t tell
9. If you add extra cotton balls to a container with cotton balls in it and squish them down to fit
in the container, what will happen to the mass and volume of the container?
A. the mass will increase and the volume will stay the same
B. the mass will decrease and the volume will stay the same
C. the mass will increase and the volume will increase
D. the mass will decrease and the volume will decrease
10. The snow on the greenhouse has a density of 100 kg/m3 and is 0.1 m deep. The roof is 5 m
wide and 8 m long. What is the load (mass) of snow on the roof?
A. 40 kg
B. 400 kg
C. 4,000 kg
D. 40,000 kg
