**Chapter One** (all sections) States of gases; p, V, T,
n and how to measure these; Ideal Gas law and laws in it (Boyle's, Charles',
Dalton's, Avogadro's); Zeroth Law of Thermodynamics; Real gases - repulsive and
attractive forces, compression factor; other equations of state (van der Waals,
virial); critical point and constants (p, V, T); principle of corresponding
states.

**Chapter Twenty Four** (section 1) Molecular motion in
gases Kinetic Theory of Gases; Maxwell distribution and types of molecular
speed; collision- diameter, -frequency, -cross section, and mean-free path.

**Chapter 24**:
Exercises
24.4 (mean speed), 5 (mean speed, mean free path, collision frequency), 7 (mean
free path). Note 8 and 9 are also good practice.

**Chapter Two **(all sections) Definitions basic to
Thermodynamics (system, surroundings, open, closed, isolated, energy, work,
heat, diathermic, adiabatic, exothermic, endothermic, etc.); First Law of
Thermodynamics and internal energy (U); State functions; Expansion work, types
(free, (isothermal) reversible, against constant pressure); Reversible vs.
irreversible processes and equilibrium; Calorimetry and thermochemistry;
Enthalpy (heat at constant pressure), relation to U and temperature dependence;
Heat capacities at constant pressure and volume; adiabatic changes, work, P,V,
T; standard enthalpy changes and Hess' law, thermochemical equations; Standard
enthalpies of formation; stoichiometric numbers; Kirchoff's law and enthalpy
temperature dependence.

**Chapter Three** (all
sections) State functions and exact differentials; partial derivatives and their
properties; partial derivative properties for all systems and for ideal gases,
and their relations (heat capacities C_{P} and C_{V}, internal
pressure π_{T}, expansion coefficient α, isothermal compressibility κ_{T},
(isothermal) Joule-Thomson coefficient μ and μ_{T}, and inversion
temperature); temperature dependence of enthalpy.

**Chapter 3**: Exercises 3.13, 18 (Joule-Thomson
coefficient).
