Basic States Of Matter Practice Test

A good score is eight correct. Answers are given at the end.

(a) 922 mol/m 3

(b) 9.22 mol/m 3

(c) 1.08 mol/m 3

(d) 33.4 mol/m 3

 

2. Suppose that a rubber band has a spring constant of 0.150 m/N for stretching forces ranging from 0 to 10 N. If the band measures 1.00 m when 3.00 N of stretching force is applied, how long with the band be when 5.00 N of stretching force is applied?

(a) 1.30 m

(b) 1.67 m

(c) 0.66 m

(d) It cannot be determined from this information.

 

3. The Mohs scale is based on a solid’s ability or tendency to

(a) boil when heated.

(b) fracture under stress.

(c) be stretched or compressed.

(d) scratch or be scratched.

 

4. A solid object with a specific gravity of less than 1 will

(a) float on liquid water.

(b) mix evenly and stay mixed with liquid water.

(c) sink in liquid water.

(d) dissolve in liquid water.

 

5. For a perfectly elastic substance,

(a) the extent of stretching is inversely proportional to the applied force.

(b) the extent of stretching is independent of the applied force.

(c) the extent of stretching is directly proportional to the applied force.

(d) the amount of force necessary to break the object in half is inversely proportional to the length of the object.

 

6. A substance with high malleability

(a) can be pounded into a thin, flat layer.

(b) is extremely brittle.

(c) readily fills any container into which it is poured.

(d) diffuses easily into other liquids.

 

7. Diffusion of gases at room temperature occurs because

(a) there are not many atoms per unit volume.

(b) the atoms or molecules move rapidly.

(c) gases always have high specific gravity.

(d) gases dissolve easily in one another.

 

8. Suppose that a sample of substance has a mass density of 8.6 × 10 3 kg/m 3 on Earth. If this sample is taken to Mars, where gravity is only about 37 percent as strong as it is on Earth, the mass density will be 

(a) 3.2 kg/m 3 .

(b) 8.6 kg/m 3 .

(c) 23 kg/m 3 .

(d) Impossible to calculate based on the information given.
