Chapter 12 begins with looking at what is temperature and how it is measured. Using interactives, the user obtains an understanding of the terminology that goes along with phase change. With the aid of graphs, the user gains an understanding of what goes on within phase changes. Exothermic and endothermic chemical reactions are also investigated within this chapter. This product uses the interactive capabilities of a computer. The chapter has an embedded end-of-chapter quiz, uses graphics, animations, user interactivity or embedded video on almost all pages. This product is designed to provide bite-sized pieces of information in an effort to enhance the scientific literacy of our next generation, not to overwhelm them with sheer quantity of information. Chapter 12 section titles: What is temperature? • How is temperature measured? • Phase Change • Phase Change Diagrams • What is heat? • Methods of Transferring Energy • Energy Change in Chemical Reactions • Chapter Concept Map • Checking Your Understanding. This product works both on a Macintosh or PC computer.
