Match the following Columns.
Both fission and fusion are nucleus reactions that produce energy, but the application are not same. Fission is the splitting of heavy unstable nucleus into two lighter nuclie and fusion is the process where two light nuclie combine together releasing vast amount of energy.
β decay produce energy.
β decay is a consequence of weak force characterized by lengthy decay time.
Exothermic nuclear reaction produce energy as the name suggest Exo (heat)
Two light nuclie fuse together (fusion reaction) Here mass of resulting nucleus is lower than mass of two reacting nuclie so energy is released.
It may be fusion or fission reaction.
