Thermodynamics problems

Note: Beyond this entry page, all problems (except in Thermal radiation) are stated and solved in Spanish. Some exercises edited in English can be found within the Lectures.
I make extensive use (both in English and Spanish) of two Latin abbreviations: ‘i.e.’ for ‘which means’ (‘es decir’), and ‘e.g.’ for ‘for example’ (‘por ejemplo’).

Problems based on the book: I. Martínez, "Termodinámica básica y aplicada", Ed. Dossat, 1992, ISBN 84-237-0810-1. Although the book is out of print, much of the contents has been updated and placed on this web site. A list of equations of interest on thermal problems can be found aside (for Thermodynamics, and for Heat Transfer).

Problems (and simple exercises) are grouped in chapters corresponding to the book above and Lectures. The solutions presented below are not intended for teaching but for checking personal work (a solved problem is no longer a problem). The learning approach may be to choose a problem statement, try to apply the generic problem solving procedures you should know, and check your results with the solution here provided; iterate until you gain confidence on how to solve new problems (not until you have memorised a bunch of them).
