GENERAL KNOWLEDGE

Detailed explanation-1: -Nuclear Fusion reactions power the Sun and other stars. In a fusion reaction, two light nuclei merge to form a single heavier nucleus. The process releases energy because the total mass of the resulting single nucleus is less than the mass of the two original nuclei. The leftover mass becomes energy.

Detailed explanation-2: -Fusion occurs when two atoms slam together to form a heavier atom, like when two hydrogen atoms fuse to form one helium atom. This is the same process that powers the sun and creates huge amounts of energy-several times greater than fission.

Detailed explanation-3: -The sun generates energy from a process called nuclear fusion. During nuclear fusion, the high pressure and temperature in the sun’s core cause nuclei to separate from their electrons. Hydrogen nuclei fuse to form one helium atom. During the fusion process, radiant energy is released.

Detailed explanation-4: -The energy in the Sun is not because of fission. It is generated in the Sun by the nuclear fusion reaction of hydrogen nuclei into helium. The fusion process occurs in the core of the Sun.
