Power Sources As we all know Earth is considered as a small part of sun, which take hundreds of year to cool, but what about Sun? Sun is far older than Earth, while it is just as it was thousand years ago. Then what is the reason for this? How a body can generate such amount of heat continuously
The common used radioactive substance in these two processes is Uranium, because Uranium has large size unstable nuclei, which can easily split into two parts. In case of Fission, the radioactive substance (Uranium atom) is splits into two small atoms “Krypton” and “Barium” having different nuclei with perfect stable condition, and huge amount of energy is released in this process. On the other hand, two atomic nuclei of deuterium and tritium are combined by sharing electron process (one atom share its electron with other atom results in bonding) to form a single atomic nuclei named Helium. In this process, immense amount of energy is released, because the resultant nuclei release energy to a large extent to make itself stable. The real life example for Fission is supernova (explosion of a star), and for Fusion is Helium gas formation on Sun. The mass change in the process is the source of nuclear energy. Fusion within the cores of the sun and other stars generates their radiating energy by fusing two hydrogen atoms to produce a helium
In case of Fission, the radioactive substance is placed on a plane surface, and enclosed in heavy machinery. Then the atomic particle neutron is projected to collide at a very high speed (70-80 times more than the regular speed). When the Neutron hits the atomic nuclei of radioactive substance, the energy of Neutron is act as breaking energy (ionisation energy), which results in splitting of one atomic nuclei into two parts and gigantic amount of energy is released during this process. The matter is not conserved (mass before reaction and after reaction) during this process, because some of the matter of fussing nuclei is converted to photons(energy). On the other hand, positive charge atomic particle collides to the one small atomic nuclei, which results in creating the vacant space for extra electron. This shortage of electron results in increasing the size of atomic nuclei, and decreases the bonding energy between protons and electrons (fundamental atomic particle of atom). Finally, second small atomic nuclei share its bonded pair of electrons with the first atomic nuclei, which results in creating a bond between the two atomic nuclei, and enormous energy is released during this process. In both these processes total energy released in Fusion is more than Fission (calculated mathematically). This process in enclosed in a lead (chemical element Pb2) cavity block, because this reaction is also
