Thermodynamics is fundamental to university curricula in chemistry, physics, engineering and many life sciences. It is also notoriously difficult for students to understand, learn and apply. This book explains the fundamental concepts with great clarity, and shows how they can be applied to a variety of chemical and life science contexts. This book's structure of unambiguous explanation of the fundamentals, followed by the application of those principles to chemical and biochemical settings, allows the reader to see thermodynamics as a tool to understand and design biological systems, rather than as an end in itself.
