- Page iii: Chapter 6 and Section 6.1 actually begin on page 139, not 137.
- Page 25: Just below equation 1.46, the curly brace should be an italic
- Page 29: Five lines below equation 1.57, "enthalphy" (in bold, no less!)
should be "enthalpy".
- Page 30: Add a closing parenthesis ")" at the very end of Problem 1.38.
- Page 72: Just below equation 3.21, the claim that S(0) is "usually" zero
or negligible is wrong (or at least misleading). For elemental solids it
is generally true. For compounds, however, there is frequently a significant
amount of entropy that comes from a multiplicity of possible molecular
orientations in the crystal, even at absolute zero. Examples include such common
substances as water (ice) and carbon monoxide. This "residual entropy" usually isn't
too hard to calculate using combinatoric methods. Glasses, which have no
regular crystal structure, have a particularly large entropy at zero temperature.
- Page 126: At the end of the first paragraph, the claim that the Curie
temperature is "typically about 1000 K" is correct for iron but incorrect for most
- Page 168: In Problem 6.39, the claim that the internal partition
function is simply the rotational partition function is correct only for
molecules that have a nondegenerate ground state. Nitrogen is an example.
Oxygen, however, has an electronic ground state with degeneracy 3, and thus
requires a further factor of 3 inside the logarithm. This factor should
be included in Problem 6.41; you can then compare your calculated value
of S to the measured value found in standard tables and obtain very
good agreement. (Orientations of nuclear spins can lead
to further degeneracy, but this contribution to the entropy is generally
not included in standard tabulations because it is present even at
- Page 228: In the fourth line of the third paragraph, "monte carlo" should
- Page 240: At the end of the first paragraph, the claim that the Curie
temperature is "around 1000 K" is correct for iron but incorrect for most
- Page 247: In the sixth-to-last line of the pseudocode Ising model
program, "m(i,j)" should be "s(i,j)".
