Hello everybody! This is my first thread and I'm just kind of discovering the forum. If I should make a presentation or should have posted this thread somwhere else, let me know please! I have plenty of books and notes about a first course in Thermodynamics, but I'm having a bit of trouble when trying to solve problems, as I have no starting point, no "guiding reference" as to how to work it out. I was wondering if somebody could recommend me some bibliography with some solved paradigmatic problems about the laws of thermodynamics, heat engines, thermodynamic potentials, phase transitions and such things... a typical first course. And not just the numerical or algebraic results of the problem, but the solution itself. Anything you can point out will be greatly apreciated: book references, web pdfs... anything! Thanks in advance!
