Entropy and its physical meaning
The book is in three parts. The first considers thermodynamics from a macroscopic viewpoint, looking at the concept of entropy and the origin of the first and second laws of thermodynamics. The second part looks at entropy from the statistical viewpoint and shows how this can be applied to various systems incluing solids and gases. Quantum effects are examined, leading to Bose-Einstein and Fermi-Dirac gases. The third part of the book looks at low temperature systems, including the different methods of achieving such temperatures and the behaviour of Helium-4 and Helium-3. The third law of thermodynamics and the unattainability of absolute zero are also discussed.
