Total questions: 15
Worksheet time: 8mins
A student wishes to determine the density of an irregularly-shaped stone.
First he finds the mass of the stone. Next he lowers the stone into a measuring cylinder
containing water.
The diagrams show the measuring cylinder before and after the stone is lowered into it.
How should the student calculate the density of the stone?
mass of stone × reading 2
mass of stone × (reading 2 – reading 1)
mass of stone ÷ reading 2
mass of stone ÷ (reading 2 – reading 1)
The diagrams show the dimensions and masses of four regular solid objects. The objects are
made from different metals.
Which metal has the greatest density?A
A
B
C
D
Diagram 1 shows a measuring cylinder containing water.
Diagram 2 shows the same measuring cylinder and water after 10 identical solid glass spheres have been added.
The mass of one of the spheres is 10g.
What is the density of the glass from which the spheres are made?
0.25 g/cm3
0.40 g/cm3
2.5 g/cm3
4.0 g/cm3
The diagram shows a cuboid block made from a metal of density 2.5g/cm3.
What is the mass of the block?
8.0 g
16 g
50 g
100 g
What is the density of the liquid?
0.5 g/cm3
2.0 g/cm3
8.0 g/cm3
10.0 g/cm3
Diagram 1 shows a piece of foam rubber that contains many pockets of air. Diagram 2 shows the same piece of
foam rubber after it has been compressed so that its volume decreases.
What happens to the mass and to the weight of the foam rubber when it is compressed?
mass increases; weight increases
mass increases; weight has no change
mass has no change; weight increases
mass has no change; weight has no change
A metal block has the dimensions shown. Its mass is 1000g.
What is the correct calculation of the density of the block?
A student wishes to determine the density of the solid block shown.
Which quantities must be known?
the area of the shaded face and the volume of the block
the area of the shaded face and the weight of the block
the mass of the block and the height of the block
the mass of the block and the volume of the block
Two cylinders are made of the same metal. Both cylinders have the same cross-sectional area but one is longer than the other.
Which quantity is the same for both cylinders?
density
mass
resistance
volume
The mass of a piece of metal is 1200 g.
A measuring cylinder contains 150 cm3 of water.
The piece of metal is put into the measuring cylinder. The water level rises to 250 cm3 and covers the metal.
What is the density of the metal?
3.0 g/cm3
4.8 g/cm3
8.0 g/cm3
12.0 g/cm3
A person measures the length, width, height and mass of a metal block with rectangular sides.
Which of these measurements must be used in order to calculate the density of the metal?
mass only
height and mass only
length, width and height only
length, width, height and mass
A liquid has a volume of 100 cm3 and a mass of 85 g.
The density of water is 1.0 g/ cm3.
How does the density of the liquid compare with the density of water?
Its density is higher than that of water.
Its density is lower than that of water.
Its density is the same as that of water
It is impossible to say with only this data.
The diagram shows the dimensions of a rectangular block of metal of mass m.
Which expression is used to calculate the density of the metal?
m × p × q
m × p × q × r
m/ (p × q)
m/(p × q × r )
Diagram 1 shows an empty measuring cylinder on a balance.
Diagram 2 shows the same measuring cylinder on the balance, but it now contains a liquid.
What is the density of the liquid?
0.2 g/cm3
0.5 g/cm3
2.0 g/cm3
5.0 g/cm3
A measuring cylinder containing liquid is placed on a top-pan balance. The apparatus is left overnight and some of the liquid evaporates.
The diagrams show the readings.
What is the density of the liquid?
0.875 g/cm3
1.14 g/cm3
1.40 g/cm3
1.42 g/cm3
