Objectives
Following your study of this chapter, you should be able to:
 explain why transitions between quantum states must usually be described in probabilistic terms
 give three reasons that statistical physics is necessary
 follow in the text how Maxwell confirmed the mean translational kinetic energy of a molecule
 state the equipartition theorem
 understand basically when quantum theory overrides the equipartition theorem
 describe what is meant by translational, rotational and vibrational modes of molecules
 write down the Maxwell velocity distribution and speed distribution
 follow the derivations of the most probable speed, the mean speed, and the root mean square speed
 name the one major characteristic makes quantum statistics different from classical statistics
 for each of the three distributors, name its properties, an example and its distribution function
 discuss the graphs of the FermiDirac factor, FFD, at various temperatures
 calculate the Fermi energy and temperature for a given element
 determine electrical conductivity and electronic contribution to the molar heat capacity of a metal
 know how electrical conductivity varies with temperature
 understand how to use the BoseEinstein distribution to derive Planck's radiation law
 use BoseEinstein statistics to account for the properties of a superfluid
