This new edition is designed for a one semester introductory course in thermodynamics, either in mechanical or aerospace engineering, or in an engineering science program. The book contains a section on the geometry of curves and surfaces, in order to review those parts of calculus that are needed in thermodynamics for discussing the thermodynamic equations of state of simple compressible substances, and their approximation by linear interpolation. It presents the First Law of Thermodynamics as an equation for the time rate of change of system energy, the same way that Newton’s Law of...
