This is another important source of energy that is obtained from the energy that is stored in the nucleus of an atom. This stored energy can be obtained by carrying out two types of nuclear reactions called nuclear fission reaction and nuclear fusion reactio..
Nuclear Reactions
Nuclear reactions are those reactions where in a nucleus when bombarded with nucleons or other sub-atomic particles; undergoes a change in its compositio..
Nuclear Membrane
This is a double-layered membrane which separates the nucleoplasm from the cytoplasm. The nuclear membrane has minute pores which allow the selective transfer of material between the nucleoplasm and the cytoplas..
Nuclear Fusion Reaction
Nuclear fusion is a reaction in which two or more light nuclei combine to form a heavier nucleus releasing an enormous amount of energy: Nuclear fusion takes place at a very high temperature of the order of 10 7 Kelvin Hence nuclear fusion reaction is called the..
Nuclear Fission Reaction
The process of splitting of a heavy nucleus into a number of light nuclei with the liberation of tremendous amount of energy and two or three neutrons is called nuclear fission. In the fissioning of the Uranium-235 isotope, some mass of Uranium disappears (or is lost) and this small m..
Heating Effect of Electric Current
Energy exists in various forms such as mechanical energy, heat energy, chemical energy, electrical energy, light energy and nuclear energ..
Renewable or Non-conventional Energy Resources
Renewable energy resources are solar radiation, wind power, hydel power, biomass and nuclear power.They can be recycled and renewed by nature. These are normally pollution free. In India, unconventional energy resources are harnessed by different metho..
Alternative or Non-conventional Sources of Energy
Due to the ever increasing demand for energy, we need to develop specific devices that can harness energy from non-conventional sources like - solar energy, energy from the sea, geothermal energy and nuclear energy. We shall discuss each non-conventional source of energy in deta..
