This updated fundamental text introduces the basic principles of thermodynamics and considers a variety of applications in science and engineering. The book has now been revised to include a fuller discussion of the van der Waals' gas, along with more coverage of phase transitions, as well as new examples and problems. The second edition also contains an entirely new chapter concerned with the world's energy problems, future requirements, and possible solutions, including discussion of a controversial, potentially new, safe method of disposing of nuclear waste. The modern coverage is compact yet self-contained and holistic in a concise and economically priced book.
