Fundamental Concepts



PROBLEMS
1. Both the hertz and the curie have dimensions of s−1. Explain the difference
between these two units.
Solution:
The hertz is used for periodic phenomena and equals the number of “cycles
per second.” The curie is used for the random or stochastic rate at which a
radioactive source decays, specifically, 1 Ci = 3.7 × 1010 decays/second.


2. Advantages of SI units are apparent when one is presented with units of barrels,
ounces, tons, and many others.

(a) Compare the British and U.S. units for the gallon and barrel (liquid and
dry measure) in SI units of liters (L).
(b) Compare the long ton, short ton, and metric ton in SI units of kg.
Solution:
Unit conversions are taken from the handbook Conversion Factors and Tables,
3d ed., by O.T. Zimmerman and I. Lavine, published by Industrial Research
Service, Inc., 1961.

(a) In both British and U.S. units, the gallon is equivalent to 4 quarts, eight
pints, etc. However, the quart and pint units differ in the two systems. The
U.S. gallon measures 3.7853 L, while the British measures 4.546 L. Note
that the gallon is sometimes used for dry measure, 4.405 L U.S. measure.
The barrel in British units is the same for liquid and dry measure, namely,
163.65 L. The U.S. barrel (dry) is exactly 7056 in 3, 115.62 L. The U.S.
barrel (liq) is 42 gallons (158.98 L) for petroleum measure, but otherwise
(usually) is 31.5 gallons (119.24 L).
(b) The common U.S. unit is the short ton of 2000 lb, 907.185 kg, 20 short
hundredweight (cwt). The metric ton is exactly 1000 kg, and the long ton
is 20 long cwt, 22.4 short cwt, 2240 lb, or 1016 kg.

3. Compare the U.S. and British units of ounce (fluid), (apoth), (troy), and
(avdp).

Solution:
The U.S. and British fluid ounces are, respectively, 1/32 U.S. quarts (0.02957
L) and 1/40 British quarts (0.02841 L). The oz (avdp.) is exactly 1/16 lb
(avdp), i.e., 0.02834 kg. Avdp., abbreviation for avoirdupois refers to a system
of weights with 16 oz to the pound. The apoth. apothecary or troy ounce is
exactly 480 grains, 0.03110 kg.


4. Explain the SI errors (if any) in and give the correct equivalent units for the
following units: (a) mgrams/kiloL, (b) megaohms/nm, (c) N· m/s/s, (d) gram
cm/(s−1/mL), and (e) Bq/milli-Curie.

Solution:

(a) Don’t mix unit abbreviations and names; SI prefixes only in numerator:
correct form is µg/L.

(b) Don’t mix names and abbreviations and don’t use SI prefixes in denomi-
nator: correct form nohm/m.

(c) Don’t use hyphen and don’t use multiple solidi: correct form N m s−2.

(d) Don’t mix names and abbreviations, don’t use multiple solidi, and don’t
use parentheses: correct form g cm s mL or better 10 µg m s L.

(e) Don’t mix names with abbreviations, and SI prefix should be in numerator:
correct form kBq/Ci.


5. Consider H2, D2, and H2O, treated as ideal gases at pressures of 1 atm and
temperatures of 293.2◦K . What are the molecular and mass densities of each.
Solution:
According to the ideal gas law, molar densities are identical for ideal gases
under the same conditions, i.e., ρm = p/RT . From Table 1.5, R = 8.314472
Pa m3/K. For p = 0.101325 MPa= 1 atm., and T = 293.2◦K , ρm = 41.56
mol/m3. Multiplication by molecular weights yield, respectively, 83.78 , 167.4,
and 749.0 g/m3 for the three gases.


6. In vacuum, how far does light move in 1 ns?

Solution:
∆x = c∆t = (3 × 108 m/s) × (10−9 s) = 3 × 10−4 m = 30 cm.
