Question

Write any four differences between Nuclear fission and Nuclear fusion.

Answer 1

Hint: A nuclear reactor which is an apparatus that produces and controls the energy that is released from nuclear fission reactions. Therefore, the energy which is released from controlled nuclear fission reaction is harnessed as heat and is used to produce steam.


Complete answer:

                NUCLEAR FISSION NUCLEAR FUSION

The nuclear fission is defined as the division of a single atom into multiple atoms of small size.	The nuclear fusion is defined as the joining of the two or more small atoms to form a large atom.
In nuclear fission it requires less energy to divide atoms into two or more ones.	In nuclear fusion a massive amount of energy is required to combine small atoms in a form of large atom.
In nuclear fission the amount of energy is released is much lower than the energy released during fusion	In nuclear fusion the release of energy during fusion is way higher than that of the fission reaction.
In nuclear fission the natural reaction never occurs in nature in normal cases.	In nuclear fusion the natural reaction takes place in stars and the sun that is natural forces.

Note: Uranium is one of the primary fuels in nuclear power plants in case of nuclear fission whereas the hydrogen isotopes are used as fuel for experimenting plants, in case of nuclear fusion. Moreover, nuclear fusion needs to be in a high density, high temperature environment and in nuclear fission the critical mass of the substance and high-speed neutrons are required.
