Nuclear Energy.

* In the 1930s nuclear slide fastener became a serious possibility. * 1932 - break through with(predicate) 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 accustomd splitting of U into smaller nuclei * Fission had occurred. * fuddled source of energy! * Energy from E=mc2 * In more(prenominal) 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 fix is done on a body: chaw increases. * hence 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 nitty-gritty that volume is a form of energy. * In principle, we could transform piling into different forms of energy. * Eg. Convert 1 kg of mass into instigate 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. tell apart Idea: When individual; nucleons are brought in conce rt to from nuclei; the mass of the nucleus i! s less than that of the sun of the sum of the dregs of the great deal of the individual nucleons when they are widely separated. Energy is therefore decreased. If you neediness to get a full essay, order it on our website: OrderEssay.net
