Question # 1

Distinguished between nuclear fission and nuclear fusion.

Ans 1: Nuclear Fission: Such a reaction in which a heavy nuclei like that of uranium splits up into two of roughly equal size along with the emission of energy is called fission reaction.
Ans 2: Nuclear Fusion:A reaction in which two lights nuclei merge to form a heavy nucleus is called fusion reaction.It require very high temperature.
