An integrated analysis of the science of thermodynamics is provided in this book. Thermodynamics is one of the most interesting parts of physical chemistry which has significantly contributed to the modern science. Being focused on a broad spectrum of applications of thermodynamics, this book accumulates a series of contributions made by veteran scientists and researchers from across the planet. This book evaluates selected topics in thermodynamics with regard to reaction rates, Planck's law, statistical, chlorination, and theory of simple liquids. The book will appeal to students engaged in post-graduate courses. It will also serve as a good source of reference for those researchers who are interested in thermodynamics.
