Study Guide- Chapter 8 What is meant by the term driving force for a phase change ? Use the solidification of a pure substance to illustrate the concept of a driving force. Review the concepts of homogeneous nucleation. Understand what is meant by the concept of a critical nucleus with respect to spontaneous growth or dissolution. Be able to derive the relationship between critical radius and undercooling. How is the barrier of the homogeneous process related to undercooling? How is the barrier determined? What factors control the rate of nucleation and undercooling and how do C-curves evolve for a transformation?
