Written for the freshman or sophomore non-science major, this text covers introductory level physics, chemistry, earth science, and astronomy within a comprehensive yet flexible presentation. With its reader-friendly style, extensive use of color, and emphasis on concepts, PHYSICAL SCIENCE 2/e affords students a smooth entrance into the world of science. Features: * Emphasizes real-world applications of science through text material and special "Focus-On" boxes. Some environmental applications are included to show another aspect of the interaction of science and everyday life. * Flexibility is built into the book, allowing the instructor to start with any section, or virtually any chapter. * The level of mathematical skill necessary to use the text is suitable for non-majors. Example problems requiring mathematical manipulations are worked out in the text to demonstrate strategies for similar problems, and all end-of-chapter problems requiring mathematics are indicated by a blue problem number. * Exercises serve as self-checks on important concepts. These quiz-like questions throughout the chapter are followed by answers and allow student to test their skills and comprehension. * Color-coding is used to both facilitate learning and enhance presentation of numerous physics principles including vectors, electrical charges, forces and fields. New to this edition: * Renowned chemist Raymond Chang of Williams College brings his expertise as a chemistry educator to the author team. The thorough revision of the chemistry section includes a complete updating as well as a new secion on soaps and detergents in Chapter 17. More emphasis is plced on the beneficial applications of chemistry in the student's world. * The earth science section has been improved and updated as well, with a new section on historical geology. * Several recent astronomical discoveries have been added to the astronomy section. A new section on the COBE experiments in Chapter 24 and up-to-date data from the repaired Hubble Space Telescope exposes students to the most recent research. * New information about quarks in Chapter 13 provides cutting edge coverage of a popular new topic in physics. * In order to further enhance student interest, the number of "Focus On" boxes, so well received in the first edition, has been increased.
