Answer
| Nuclear fission | Nuclear fusion | |
|---|---|---|
| (a) | Nuclear fission is the process of breaking of a heavy nucleus in two nearly equal fragments with the release of energy. | Nuclear fusion is the process of combining light nuclei to form a larger nuclei at a very high temperature and pressure with the release of energy. |
| (b) | This reaction is possible at ordinary temperature and ordinary pressure. | This reaction is possible only at a very high temperature (≈ 107 K) and a very high pressure. |
