This text contains a comprehensive and rigorous treatment of classical thermodynamics. Noted for its treatment of the second law, it features theory and application, and includes a functional new format utilizing colour, new design problem sections, and animation. It contains a thorough development of the first and second laws of thermodynamics including entropy production and new material on the international temperature scale and refridgerants. A problem-solving methodology is carried through each chapter with examples, illustrative problems and chapter-end problems, encouraging students to develop an orderly approach to problem solving, to think systematically and reduce typical errors.
