Question

Name the process used to harness nuclear energy these days. Explain it briefly. List two advantages of using nuclear energy in place of fossil fuels. 

Answer 1

Process used to harness nuclear energy is nuclear fission.

The nucleus of a heavy atom like uranium is bombarded with low energy neutrons, the heavy nucleus now spilts into lighter nucleii and tremendous amount of energy is released.

Advantages :

The fission of an atom of uranium produces 10 million times the energy produced by the combustion of an atom of carbon from coal.

Less use of fossil fuels implies lower emission of greenhouse gas.
