Hi Rifky!Hope you're well where you're at! I actually just took thermodynamics this past quarter, and my course used Smith Van Ness!
Unfortunately we didn't cover the entire book-are there specific questions that you might have or problems that you're concerned about? I'll be better to offer assistance if you can pinpoint where you need help. Also be sure to use the version that has both the numerical solutions and the non-numerical ones (aka the proofs).Best,Brandan
