In this section, we wish to extend our current statistical analysis to nally show how it represents macroscopic events. In particular, w

We will now spend the next part of the course re-examining the whole meaning of terms like
temperature, pressure, entropy etc. from a statistical viewpoint. We wish to build up al
We now turn to consideration of a new concept. This concept gives us, ultimately, a
fascinating new perspective into the second law of thermodynamics.
It turns out that we can define a new STATE variable, in addition to our current state

As in previous sections, there is a certain element of revision in this part of the course. However,
as before we will also extend your current understanding as we pass through this sectio

The Laws of Thermodynamics, and Entropy.
Thermodynamics is basically the study of the transport of heat. Although this may seem
to be a somewhat restrictive topic, we will see that this is far from true. The topic

Transport Phenomena in Gases.
Some of the important properties of gases which can be predicted from kinetic theory are:
(i) VISCOSITY - rate of transport of momentum
(ii) THERMAL CONDUCTIVITY - rate of transport of kinetic energ
Partition Functions for Multi-particle Systems.
Up until now we have been largely concentrating on the partition function for a single particle.
We now wish to extend this discussion to include multi-particle systems, although we still

We are now ready to begin statistical mechanics in earnest. However, before beginning this
section we rst need to get familiar with a few concepts.

It is in this section that we will nally begin to see the power of the statistical approach to
thermodynamics. Before doing so, however let us remind ourselves of a couple of

Ideal Gas Equation.
In this section, we will once again visit concepts which we have already discussed, but will
re-examine them in a new light. Whereas earli

Traditionally, students have seen some simple thermodynamics by third year. In more
recent years, this is not always so. Hence this chapter presents an overview of this
