Question
a) Name the process, nuclear fission or nuclear fusion, in which energy releasedper unit mass is more.(b) Name the process fission or fusion which is possible at ordinary temperature.(c) State one difference between nuclear fission and fusion.
Solution
a) The process in which energy released per unit mass is more is nuclear fusion. In nuclear fusion, two light nuclei combine to form a heavier nucleus, releasing a large amount of energy. This is the process that powers the sun and other stars.
b) Neither nuclear fission nor nuclear fusion is possible at ordinary temperatures. Both processes require extremely high temperatures. However, in terms of feasibility, nuclear fission is more achievable on Earth as it requires lower temperatures compared to nuclear fusion.
c) One difference between nuclear fission and fusion is the process involved. In nuclear fission, a heavy nucleus splits into two or more smaller nuclei along with the release of energy. On the other hand, in nuclear fusion, two light nuclei combine to form a heavier nucleus, releasing energy.

Nuclear fission and nuclear fusion are both processes by which the atoms of matter are altered to create energy, but they are opposite processes. In fission, one atom splits into two, whereas fusion combines two lighter atoms into a larger one. Although both processes release energy, fission is the more controllable reaction. It is used in nuclear power plants to produce electricity, usually with Uranium-235. Fusion, on the other hand, is the process that powers the sun. Fusion releases an enormous amount of energy, several times that of fission. Fusion is used not for power plants but for thermonuclear weapons.Which organizational structure does this text primarily use?
