This is the first modern approach to thermodynamics written specifically for an undergraduate course. It covers the fundamental modern formalism that relates rates of entropy production to irreversible processes, and its historical context; describes basic applications of the formalism and continues with a number of additional applications that instructors can use according to their particular degree program. These chapters cover thermal radiation, biological systems, small systems including nano systems, classical stability theory, and principles of statistical thermodynamics. A wide range of examples appear throughout the book showing the student a wide range of applications in biological, engineering and atmospheric systems. Introduction to Modern thermodynamics will prove invaluable to chemists, chemical, engineers, physicists, material scientists, industrial and mechanical engineers taking a first course in thermodynamics. * First modern approach to the subject written for undergraduates * Suitable for a variety of degree programs with an extensive range of applications and examples drawn from biological, engineering, atmospheric and small systems including nano systems * Includes Onsager reciprocal relations and dissipative structures * Numerous examples and exercises in each chapter * Mathematical codes for solving complex problems * Dedicated website for students and instructors
