Lecture no. 24 from the course: The Joy of Science
Taught by Professor Robert M. Hazen | 29 min | Categories: The Great Courses Plus Online Science Course
Change is a hallmark of the material world. Wood burns, glue hardens, eggs cook, dead organisms decay, carbon graphite under high pressure becomes a diamond. Physical transformations reflect changes in the arrangement of atoms and their chemical bonds. What distinguishes a phase transformation from a chemical reaction? What are types of chemical reactions, and how do they occur?
