Assertion (A): In the process of nuclear fission, the amount of nuclear energy generated by the fission of an atom of uranium is so tremendous that it produces 10 million times the energy produced by the combustion of an atom of carbon from coal.Reason (R): The nucleus of a heavy atom such as uranium, when bombarded with low-energy neutrons, splits apart into lighter nuclei. The mass difference between the original nucleus and the product nuclei gets converted to tremendous energy.(a) Both A and R are true and R is correct explanation of the Assertion.(b) Both A and R are true but R is not the correct explanation of the Assertion.(c) A is true but R is false.(d) A is false but R is true.
(a) Both A and R are true and R is correct explanation of the Assertion.
Explanation
Nuclear Energy
1. It is a non-conventional source of energy.
2. It is harnessed by a process called nuclear fission.
3. Uranium-235 is used as a fuel in a nuclear reactor.
4. It splits apart into lighter nuclei when bombarded with low-energy neutrons.
5. After this the mass difference between the original nucleus and the product nuclei gets converted to tremendous heat energy.
6. For example, it produces 10 million times the energy produced by the combustion of an atom of carbon from coal.
8. A nuclear reactor is designed to produce electrical energy.
