5.

Susan made measurements to determine the density of a yellow colored metal in the shape of a rectangular block. Her results are shown below.

Block length

12 cm

Block height

2 cm

Block width

4 cm

Mass

384 g

The density of the block was:

 

a) 21.33 g/cm³

 

b) 4 g/cm³

 

c) 6912 g/cm³

 

d) 8g/cm³

6.

The density of 1 cm³ of pure water is 1g/cm³. What is the density of 250 cm³ of pure water?

 

a) 250g/cm³

 

b) 1cm³

 

c) 1g/cm³

 

d) You cannot determine its density without knowing the mass of the water.

7.

Jupiter has a much greater mass than the Earth. An object with a mass of 27.54 g on Earth would :

 

a) Have the same mass on Jupiter

 

b)Have a greater density on Jupiter than on Earth

 

c)Have the same weight on Jupiter

 

d)Be lighter on Jupiter (because Jupiter is in space).

8.

Colored water is poured into each of the funnels shown in the diagram below.
Which of the following best describes what would be observed?

 

a) Water pours through the funnel into both tubes because the tubes are empty.

Two test tubes, labelled A and B. Tube A contains a stopper with one hole in it. The stopper has a funnel inserted into it. Tube B has a funne inserted into it, no stopper.
 

b) Water stays in the funnels and does not enter either of the tubes.
This is because air has density.

 

c) Water stays in funnel A and does not enter the tube, but enters tube B.
This is because air is trapped in tube A, but can escape from tube B.

 

d) Water stays in funnel A and does not enter the tube, but enters tube B.
This is because air has mass.

9.

The picture below shows a type of of balloon. Which of the following best describes why this type of balloon floats in air?
Because the balloon is filled with:

 

a) Hydrogen gas that is lighter than air

Labelled illustration of a hot air balloon
 

b) Hot air that is lighter than the surrounding cold air

 

c) Hot air that is less dense that the surrounding cold air

 

d) Helium gas that is less dense than air

10.

A student put two identical nails, each with a mass of 12g, into a graduated cylinder containing 120 cm³ of water. After adding the two nails the water level rose and the reading on the cylinder was 128 cm³ . What was the density of the nails?

 

a) 8g/cm³

 

b) 3g/cm³

 

c) 6g/cm³

 

d) 10cm³/g

11.

When most matter gets hotter, it:

 

a) Increases in mass and decreases in volume

 

b) Decreases in mass and decreases in volume

 

c) Stays at the same mass and increases in volume

 

d) Stays at the same density but increases in volume

12.

The Alaska pipeline was built with zigzags at certain intervals. These zigzags were included to allow for:

 

a) Changes in the mass of the pipe with changes in temperature

 

b) Changes in the migratory routes of elk and moose

 

c) Changes in the permafrost below the pipeline

 

d) Changes in the length of the pipeline with changes in temperature
