This work presents an intergrated approach to thermodynamics and heat transfer suitable for undergraduates on a mumber of courses. Topics covered include: the First Law of Thermodynamics, fundamentals and applications; the Second and Third Laws; thermodynamic cycles including the Carnot, Rankine and Otto Cycles; conduction of heat, under both steady and non-steady conditions; forced and natural convection of heat; radiation heat transfer; and introductory statistical thermodynamics. In addition there are many numerical examples throughout the text and at the end of each chapter.
