Thermodynamics is a fascinating subject. I like this book because it proves every equation it gives, and you can sort of work some out. These kind of proofs are sort of weird at first because it makes some very simple statements, introduces a bit of notation and then arranges things and says 'look, this is what we have arrived at in our discussion'. And then you look at it, and think about it, and it seems so wonderful that a complicated statement or property or equation or something in thermodynamics can be drawn out of something so simple, with some clever analysis. I am kind of the studious type so textbooks with questions suit me better, but if you are just looking for something to read, then by all means buy this book. I might add that it is quite short, but don't be too hung up on that (unless you know a lot about the subject) because as I say it is largely equations, which don't take up a lot of room.
