Thermodynamics: An Interactive Approach employs a layered approach that introduces the important concepts of mass, energy, and entropy early, and progressively refines them throughout the text. To create a rich learning experience for today?s thermodynamics student, this book melds traditional content with the web-based resources and learning tools of TEST: The Expert System for Thermodynamics. TEST is an interactive platform that offers smart thermodynamic tables for property evaluation and analysis tools for mass, energy, entropy, and exergy analysis of open and closed systems. Features ? Throughout this book physical arguments are used to simplify concepts, support mathematical arguments, and explain numerically derived conclusions Examples present opportunities to apply analysis, offer detailed solutions, and What-If scenarios Did You Know? section offers interesting and helpful facts about materials and engineering concepts Problems at the end of each chapter apply concepts and refine engineering analysis Property Tables allow for quick reference of material properties, as well as saturation and vapor tables, for many elements and compounds
