This is my third reading of this book. It's a basic introduction to thermodynamics. Discusses first and second law of thermodynamics, reversibility, heat engines (Otto and Carnot cycles), power plants, and just barely touches on statistical mechanics. It's only 102 pages, so you can imagine it doesn't develop anything completely. But it's illustrative and does give clear explanation of what it does cover.
This is a 1983 republication by Dover of a work originally published by McGraw-Hill in 1969.
He uses the same example Feyman does in his Lectures on Physics to explain the first law. I'm not sure, but I think he also uses a common explanation for reversibility. Discusses heat capacity, but doesn't explain what it is. Does develop the notion of entropy very nicely. Also a pretty clear derivation of the Boltzmann distribution.
I expect to read this only once more - at most twice. It's a quick read, and worth it as a refresher (I took thermodynamics in university), or as a fair introduction to the layman. But I plan to start on Feyman's lectures later this year or early next. It was cheap (when I bought it), only $3.75 (usa). Man, I love Dover.
