→ Flowing water is a renewable source of electric energy. This phenomenon is utilized in nuclear power plants. (c) A sizeable amount of fuel can be reclaimed by processing the spent fuel material. Wind is the natural phenomenon caused by pressure differentials due to unequal heating of land and water masses on the surface of the earth. It should be able to do a large amount of work for each unit of mass or volume. 1 atomic mass unit = 931 million electron volts1 u= 931 MeV Energy in usable form is dissipated to the surroundings as less usable form. A very large amount of energy can be produced by a nuclear process on using very small amount of nuclear fuel in a nuclear reactor. The world's largest geothermal electric power plant, at Geysers Steam Field, California, uses this method to generate electricity. Your email address will not be published. (d) The source of energy is free and renewable. → Exploiting any source of energy disturbs the environment in some way or the other. The fission reaction of uranium-235, (or plutonium-239) is deliberately allowed to go out of control so as to produce an enormous amount of energy in a very short time. It is the source of the conventionally used fuels that are used in our country. Colder water from the surface below is utilized to condense ammonia vapour which is then channelized to the surface to repeat the cycle. Suppose a slow neutron is absorbed by a nucleus of U-235 in a block of uranium. In this process, U-235 itself does not undergo fission. The steam produced by burning fossil fuels nans the turbine to produce electricity. This document is highly rated by Class 10 students and has been viewed 2622 times. It turns out that 1 u of mass, when converted into energy, releases about 931 MeV of energy.
The document Geothermal Energy and Nuclear Energy Class 10 Notes | EduRev is a part of the. → Energy obtained from the sun is called solar energy. Sun has been radiating energy from the past 5 billion years and will continue to do so at the same rate for another 5 billion years or more. (4) Water absorbs heat from hot sodium and boils to form steam. Fusion has been used to make nuclear bombs that are more powerful than those based on fission. out Class 10 lecture & lessons summary in the same course for Class 10 Syllabus. perfect preparation. Graphite is called, uranium rods are inserted boron rods B. Boron rods are called, prevent the fission reaction from going out of control. Composition of Bio-gas: Bio-gas is mainly composed of methane (up to 75%), C02 (25%) and traces of other gases such as nitrogen and hydrogen. (1) The controlled fission of uranium-235 in the nuclear reactor produces a lot of heat energy. (8) This water is again sent to the heat exchanger for forming fresh steam. The energy so produced can be easily transformed into electrical energy.
