Energy released per fission of a nucleus is of the order of 200 MeV whereas that per fusion is of the order of 10 MeV. But a fusion bomb (Hydrogen bomb) is said to be more powerful than a fission bomb. Explain why? |

Answer» Solution :(i) Energy produced per fusion is LESS but the number of nuclei per unit mass is larger on ACCOUNT of smaller mass number. (II) So, energy released per unit mass is GREATER. On the other hand, the fissionable materials have HIGH atomic weight. (iii) The number of fission nuclei per unit mass is less. So, energy released is less. |
