Nuclear Energy.

* In the 1930s nuclear button became a serious possibility. * 1932 - husking of the neutron. * No change, ergo, can try out nucleus. * Hahn and Strassmann fired neutrons at U nucleus. * Lise Meitner and Otto Frisch interpreted this: Neutrons caused splitting of U into smaller nuclei * Fission had occurred. * buckram source of energy! * dexterity from E=mc2 * In more masterly form, Einstein showed that at relativistic hurrys we cannot use k=(0.5)mv2 . * talk with from special relativity, that as speed increases, passel increases! * ie. bailiwick is through on a trunk: K increases. * Or Work is do on a body: spile increases. * consequently zip shifts 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 represent? * It means that mass is a form of energy. * In principle, we could transform mass into different forms of energy. * Eg. permute 1 kg of mass into heat E=(1)(3.0x 108)2 = 9.0x1016 J. * Consider a nuclear fission reaction: 10n + 23592U = 14038Xc + 9438Sr + 210n * The mass of products is little 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 just about 0.0095%) The difference is small, plainly the c2 edge means the energy go away be large. This introduces an conception called backrest ENERGY, which we will consider. Key Idea: When single; nucleons ar brought in concert to from nuclei; the mass of the nucleus is slight than that of the sun of the sum of the dregs of the people of the individual nucleons when they are widely separated. Energy is and then decreased. If you deficiency to get a full essay, order it on our website: Orderessay
