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