About Product
This book is designed to meet the academic aspirations of inquisitive young minds of undergraduate students. The main objective of the book is to provide students with clear and logical presentation of basic concepts and principles of thermal and statistical physics. The book has been divided into two parts. The first part deals with the kinetic theory of gases, transport phenomena, equation of state, laws of thermodynamics entropy, production of low temperature, thermal conduction and the nature of thermal radiation.All the equations and thermodynamic relations have been expressed in terms of specific values of extensive variables and these variables have been denoted by lower case letters (v, q, u, s, cv, c ). The intensive variables have been denoted by upper case letters (P, T).A large number of solved examples have been provided to make the audience feel confident in applying the principles of thermodynamics to various phenomena.Part II of the book presents lucid and systematic exposition of the fundamental principles of the most fascinating, exciting, timulating and challenging subject-statistical physics. In this part of the book, attempts have been made to present most difficult concepts of statistical physics in most elementary form.It begins with the description of microscopic state of the system. Both quantum and classical methods of description of microscopic state have been discussed. The classical description of a state requires the concept of phase space, μ -space, γ -space and density of states. All these concepts are developed here.Chapter II is devoted to the development of the concept of ensemble formulation of statistical mechanics. The two fundamental postulates of statistical mechanics - principle of equal a priori probability and ergodic hypothesis are discussed here. Then Livoulle?s theorem and the three kinds of ensembles - microcanonical, canonical and grand canonical ensembles are introduced. Canonical distribution function is derived in this section.Chapter III gives a brief account of thermodynamic functions-energy, entropy, free energies and their connection with partition function.Chapter IV describes the classical statistics. Maxwell-Boltzmann statistics for distinguishable particles and Maxwell?s speed distribution function are derived first.Chapter V deals with the consequences of indistinguishability of particles and the need for quantum statistics. Bose-Einstein and Fermi- Dirac statistics have been derived.Chapter VI is devoted to the study of some important applications of F-D statistics such a Sommerfeldʼs free electron theory of metals, electronic heat capacity, Richardson-Dushmann theory of thermionic emission, and B-E statistics to Ideal Bose gas and Planckʼs radiation law. This chapter ends with discussion on validity criterion for classical regime and the comparison of M-B, B-E and F-D statistics.Chapter VII and VIII present various types of partition functions and their applications to specific heat problems. Einstein and Debye models for calculation of specific heat are given in these chapters.Chapter IX discusses the well-known Random walk problem, Saha Thermal Ionization formula, Pauli-Paramagnetism of conduction electrons and the concept of negative temperatureIf you want to buy this book online, kindly click on the following link:Amazon.in
