Chapter 2 Particles of Matter
2.1 The Submicroscopic World Is Super-Small
1) A biological cell is best described as ________.
A) macroscopic
B) microscopic
C) submicroscopic
D) nanoscopic
Answer: B
Diff: 2
Learning Obj: 2.1
2) How would you describe the size of the following object?
a blood cell A)
microscopic
B) macroscopic
C) submicroscopic
D) all of the above
E) none of the above
Answer: A
Diff: 2
Learning Obj: 2.1
3) How would you describe the volume of the following object?
the amount of water in a swimming pool
A) microscopic
B) macroscopic
C) submicroscopic
D) all of the above
E) none of the above
Answer: B
Diff: 2
Learning Obj: 2.1
, 4) A TV screen looked at from a distance appears as a smooth continuous flow of images. Up
close, however, we see this is an illusion. What really exists are a series of tiny dots (pixels).
This is similar to a chemist's view of matter in that ________.
A) the fundamental particles of matter can also be seen when looked at closely with a magnifying
glass
B) on the submicroscopic level, chemist's find that matter is made of extremely small particles,
such as atoms and molecules.
C) anything that a chemist can see, touch, hear, smell, or taste is an illusion
D) elements are made up of only three basic types of matter
Answer: B
Diff: 2
Learning Obj: 2.1
5) Red colored Kool-Aid crystals are added to a still glass of hot water. The same amount of
crystals are added to a second still glass filled with the same amount of cold water. With no
stirring, which of the following would occur?
A) Without stirring, both glasses will reach uniform color in the same amount of time
since they both contain identical amounts of water.
B) The glass of cold water will reach a uniform red color first since there are no heat
convection currents to impede the distribution of the dye.
C) The glass of hot water will reach a uniform red color first since the higher kinetic
energy provides for faster moving molecules to more quickly distribute the dye.
D) The Kool-aid crystals will never dissolve in either glass until the glasses are stirred.
Answer: C
Diff: 1
Learning Obj: 2.1
6) The same amount of red colored Kool-Aid crystals are added to a still glass of thick sugar
water and a still glass of distilled water. Both are the same temperature. Neither is stirred. Which
should become uniform in color first?
A) The glass of distilled water should become uniform in color first.
B) The glass of thick sugar water should become uniform in color first.
C) Both glasses will become uniform in color at exactly the same time.
D) Without stirring, it is unlikely that either glass will ever become uniform in color. Answer: A
Diff: 3
Learning Obj: 2.1
7) You take 50 mL of small BB's and combine them with of large BB's and you get a total
of 90 mL of BB's of mixed size. Which of the following statements best explains this?
A) Since the density of the small BB's is less than that of the large BB's their volumes do not add
directly to one another.
B) This is not possible since the Law of Conservation of Volume would be violated.
C) The total volume actually gets larger since mixing the BB's would leave additional air space
because of the difference in size of the two BB sets.
D) Many of the smaller BB's are able to fit within the pockets of space that were empty within
the of large BB's.
