This comprehensive text is based on the authors' course notes, refined and updated over 15 years of teaching. The core of the text focuses on water and its transformations. Four chapters lay the foundation, from energy conservation to the ideal gas law, specific heat capacities, adiabatic processes, and entropy. An extensive chapter treats phase transitions of water, and a lengthy discussion of the van der Waals equation sets the stage for phase diagrams. Free energy is applied to determining the effect of dissolved substances, total pressure, and size on vapor pressure. The chapter on moist...
