Test Description: Problems to practice density.
Instructions: Answer all questions to get your test result.
1) Which of the following is the correct formula to determine density?
A
Volume times mass (V x M)
B
Mass divided by volume (M/V)
C
Mass times volume (M x V)
D
Volume divided by mass (V/M)
2) If an object has a mass of 3 grams and a volume of 6 milliliters, what will its density be?
A
2 g/ml
B
0.5 g/ml
C
1 g/ml
D
3 g/ml
3) If an object has a mass of 2 grams and a volume of 1 milliliter, what will its density be?
A
2 g/ml
B
1 g/ml
C
4 g/ml
D
0.5 g/ml
4) Objects A and B have the same mass, but object B is bigger and has more volume. How does the density of object A compare with the density of object B?
A
Object A is less dense than object B because it has less mass
B
Object A is more dense than object B because it has less volume
C
Object A is more dense than object B because it has more volume
D
Object A is less dense than object B because it has more mass
5) If oil floats on water, what do we know about its density?
A
Oil is more dense than water
B
Oil is less dense than water
C
Oil doesn't have density because it is a liquid
D
Oil and water have the same density
6) An object has a mass of 5 grams and a volume of 5 milliliters, what will its density be?
A
3 g/ml
B
1 g/ml
C
0.7 g/ml
D
5 g/ml
7) You put a can of Coke and a can of Diet Coke into a bowl of water and you notice that the Coke sinks while the Diet Coke floats. How do their densities compare?
A
The Coke is less dense than the Diet Coke
B
The Diet Coke is less dense than the Coke
C
The Diet Coke and Coke have the same densities
D
The Diet Coke is more dense than the Coke
8) Water has a density of 1 g/ml. Will an object that has a density of 3 g/ml sink or float in water? Why or why not?
A
It will sink because it is less dense than water
B
It will sink because it is more dense than water
C
It will float because it is more dense than water
D
It will float because it is less dense than water
9) Water has a density of 1 g/ml. Will an object that has a density of 0.8 g/ml sink or float in water? Why or why not?
A
It will float because it is less dense than water
B
It will sink because it is less dense than water
C
It will sink because it is more dense than water
D
It will float because it is more dense than water
10) Why does ice float on liquid water?
A
Because ice is colder than liquid water
B
Because water is more dense than ice
C
Because they are both made of hydrogen and oxygen
D
Because water is less dense than ice
