Document Summary
5. 1. 1 chain reaction: a reaction in which a product leads to additional reactions. Fission can lead to chain reactions that help provide the energy found in a substance like uranium. Total work done is therefore greater than the work required to trigger the reaction. 5. 1. 2 exponential growth: when a reaction leads to at least 2 additional reactions. Eg, doubling: if n0 is initial amount of product and n is amount after x iterations of the reaction, then. Doubling growth example: cell division (leads to growth of an organism, population growth of bacteria and virus, etc) 5. 2. 1 fission: the splitting of an atom"s nucleus into two lower-mass nuclei ( fission fragments ) Energy production expressed in mev (1 mev = 1 million ev; 1 joule 6 trillion mev) Mev is small, but applies to only a single atom"s nuclei. Induced by firing a neutron at a fissionable nucleus.
