A Condensed Collection of Thermodynamic Formulas

Harvard University Press has partnered with De Gruyter to make available for sale worldwide virtually all in-copyright HUP books that had become unavailable since their original publication. The 2,800 titles in the “e-ditions” program can be purchased individually as PDF eBooks or as hardcover reprint (“print-on-demand”) editions via the “Available from De Gruyter” link above. They are also available to institutions in ten separate subject-area packages that reflect the entire spectrum of the Press’s catalog. More about the E-ditions Program »

The thermodynamic formulas most often used in theoretical and practical work state various relations between first and second derivatives of various thermodynamic functions. There are a very large number indeed of such relations, and the discovery of the one needed in any particular problem usually takes considerable time, especially if one is not working continually in the field. In this collection of formulas, means have been found for condensing into very small space all the possible relations of this character. A number of problems are worked in detail, illustrating various uses of the formulas, and methods are described of extending the formulas to systems exposed to more general external forces than the conventional hydrostatic pressure.
