![]() That motion is then used to generate electrical energy or other forms of power. With simple mechanics, the energy of an object’s motion is put to work: using weights under the influence of gravity, flowing water, or moving air to turn a wheel or turbine. If you have any doubt on this topic you can ask me in the comment section.When it comes to generating power and energy, physics gives us plenty of options. The answers for all of these questions can be found inside this article. Why is nuclear fission required before nuclear fusion?.What are the conditions for nuclear fusion?.Why is the nuclear fission is called a chain reaction?.Why do we need a low speed neutron for nuclear fission?.Difference between nuclear fission and nuclear fusion Important questions: Used to produce atom bomb and electricity. this process happens repeatedly after first reaction. No neutron is required for nuclear fusion. Low speed neutron required for nuclear fission. In this process two lighter nuclei combine into a larger nucleus. In this process a heavy nucleus breaks into two smaller nuclei. Difference between nuclear fission and nuclear fusion in tabular form SL No. The Sun can supply such a huge amount of light energy only due to nuclear fusion process inside it.Nuclear fusion is used to produce hydrogen bomb.In this process hydrogen atoms combine to form helium atom and releases huge amount of energy.Ĥ 1H 1 + heat = 2He 4 + 2 1e 0 + energy Uses of nuclear fusion The Sun can generate such amount of energy by the nuclear fusion process on it. The source of all energy on the Earth is the Sun. Therefore, to get nuclear energy from nuclear fusion, the nuclear fission process has to take place first. Now, the source of this huge energy is nuclear fission. We need high temperature or heat energy to combine even two lighter nuclei by nuclear fusion process.But the huge amount of required energy to combine two heavy nucleus is not possible to generate. Therefore, to combine these two light nuclei we need relatively smaller external energy. Because two lighter nuclei will exert smaller electrostatic repulsive force. Only the nuclei of light elements like hydrogen and hydrogen-like elements can be used in nuclear fusion.There are two main conditions for nuclear fusion reaction. Nuclear fusion requires a huge external energy to combine the nuclei. This is the opposite phenomena of nuclear fission. Nuclear fusion is a nuclear phenomena in which two or more smaller nuclei combine to form a new and heavy nucleus. It also has the uses in nuclear reactors to produce electricity.Nuclear fission the application to produce atom bomb.The examples of nuclear fission are as followings – Nuclear fission has the uses in producing atom bomb.This is why nuclear fission is known as a chain reaction. neutrons form in a chain way and these neutrons take part in further nuclear fission reactions. ![]() In this cumulative process 1, 3, 9, 27, 81,…. These three neutrons also take part in another three nuclear fission and produces 9 neutrons after breaking those heavy nuclei. During the first interaction of a neutron and the heavy nucleus, the nucleus breaks into two parts and also creates 3 new neutrons. One can perform several consecutive reactions by using only one neutron. This is why a slow neutron is used in nuclear fission. It cannot absorb the energy of a high-speed neutron because of less interaction time. This breaking up of heavy nucleus occurs after absorbing the energy of that slow neutron. In nuclear fission, a neutron of low speed is required to collide with the heavy nucleus to break it into two parts.Heavy nucleus breaks into two nucleus of almost equal masses.Nuclear fission is a nuclear phenomena in which a heavy nucleus breaks up into two nucleus of almost equal masses (usually in 5:7 ratio) after colliding with a slow neutron. Difference between nuclear fission and nuclear fusion What is nuclear fission?.In this article, we are going to discuss the definition, properties, examples, uses and differences between nuclear fission and nuclear fusion in tabular form. But these two phenomena occur in different conditions and the amount of heat generation is also different in these two phenomena. Nuclear fission and nuclear fusion are two nuclear phenomena to produce nuclear heat energy.
