Explanation:
Detailed explanation-1: -Inside the sun, energy is generated due to the nuclear fusion of hydrogen nuclei into helium. Nuclear fusion is the source of Sun’s energy. At the core where temperature and pressure are very high, hydrogen atoms fuse into helium atom and release energy in the form of Gamma rays.
Detailed explanation-2: -The reaction that happens in the sun fuses two Hydrogen atoms together to produce Helium. It looks like this in a very simplified way: H + H → He + ENERGY. This energy can be calculated by the famous Einstein equation, E = mc2.
Detailed explanation-3: -Amount of energy released in one fusion reaction = 4.3 x 10-12Joules/reac.
