Bruce Fegley has scripted a comprehensive text in classical phenomenological thermodynamics The greatest strength of this volume is its attention to the needs of the student. I hope its greatest value will be in drawing a new generation to apply classical thermodynamics in the geosciences with intellectual rigor. <b>--Meteoritics and Planetary Science, 2013</b></p> This book covers thermodynamics from a different angle. Fegley puts a much stronger emphasis on the effects of pressure or the equilibrium between materials as they occur in the geological or planetary sciences this focus is demonstrated in the examples and problems discussed in each of the 12 chapters. <b>--CHOICE April 2013</b></p>
