The quality of human life in relation to the chemical principles that affect it is described in understandable terms to the non-science student, with a strong focus on these applications to the total human experience. Understanding replaces memorisation as students learn about the importance of chemistry in such relevant areas as ozone depletion, nutrition, conservation and everyday household goods. Features: * The text's modern applications help maintain its reputation as an up-to-date approach to basic chemistry. * Tremendous coverage on energy and environmental-related issues. New to this edition: * More in-depth material on the gases in Chapter 7, provides students with a more comprehensive understanding of the three states of matter. * "Discovery" boxes encourage students to attempt simple experiments on their own without the use of extensive laboratory equipment. * A greater variety and number of end-of-chapter questions with more quantitiative problems for applicable chapters. * New boxed features, including "Frontiers in the World of Chemistry" and "Science and Society" offer in-depth treatment of particularly important and current topics. * Improved correlation to the World of Chemistry Videotape Series.
