Nuclear Energy.

* In the 1930s nuclear life force became a serious possibility. * 1932 - find of the neutron. * No change, ergo, can probe nucleus. * Hahn and Strassmann fired neutrons at U nucleus. * Lise Meitner and Otto Frisch interpreted this: Neutrons ca expendd splitting of U into smaller nuclei * Fission had occurred. * unwavering source of energy! * Energy from E=mc2 * In more than masterful form, Einstein showed that at relativistic speeds we cannot use k=(0.5)mv2 . * flirt with from special relativity, that as speed increases, passel increases! * ie. bailiwick is through on a body: K increases. * Or work at is done on a body: lot increases. * consequently ENERGY transforms into Mass. * Einstein: Instead of k=(0.5)mv2 We must use K=(m-m0)c2 Or K = mc2-m0c2 As K = E-m0c2 E=m0c2+K Where E = total energy. * What does E=mc2 mean? * It centre that band is a form of energy. * In principle, we could transform mickle into different forms of energy . * Eg. Convert 1 kg of mass into mania E=(1)(3.0x 108)2 = 9.0x1016 J. * Consider a fission reaction: 10n + 23592U = 14038Xc + 9438Sr + 210n * The mass of products is less than the mass of the reactants! ie. 23592U 235.0439 u 14038Xc 139.9054 u n 1.008 u 9438Sr 93.9063 u 210n 2.

016 u 236.0519 u 235.8277 u Difference = 0.2242u ( or about 0.0095%) The difference is small, plainly the c2 term means the energy will be large. This introduces an conception called BINDING ENERGY, which we will consider. make out Idea: When indi vidual; nucleons are brought in concert to f! rom nuclei; the mass of the nucleus is less than that of the sun of the sum of the dregs of the commonwealth of the individual nucleons when they are widely separated. Energy is therefore decreased. If you wish to get a full essay, order it on our website: OrderCustomPaper.com
