How does the Sun produce solar energy?

Answer 1

The extreme temperature and pressure near the center of the Sun is enough to cause the fusion of the bare nuclei found there. The primary reaction in the Sun is hydrogen fusing to helium. This releases energy by the annihilation of some of the mass of the two atoms. As helium builds up in the core, these atoms are also fused into heavier elements. Nucleosynthesis continues to the production of iron, whose fusion does not release any net energy. The s-process (neutron capture) can form atoms up to bismuth, but again does not release energy.

Answer 2

In the Sun, almost all of the fusion energy is released by the fusion of hydrogen into helium. The process, which requires high density and temperature, produces energy through the loss of mass. Through a three-step process (each creating energy), a pair of hydrogen atoms combine to form a single helium atom.

The energy is released as gamma rays (photons) and neutrinos. Eventually the energy is transferred from the core to the outer layers of the sun, where it is released as solar radiation.

It is this radiated energy that illuminates and heats the Earth.

Answer 3

Nuclear fusion involves the combining (fusion) of two relatively light elements into one slightly heavier element. In the case of the Sun, the primary reaction is the fusion of hydrogen (four protons) into helium (two protons and two neutrons). The energy comes from the fact that the residual binding energy required to sustain helium is less than the energy required to sustain hydrogen, so this energy is released.

It is not a lot of energy per reaction, about 4.2 x 10-12 joules per reaction, but there are a lot of concurrent reactions, estimates being around 9.2 x 1037reactions per second, hence there is a lot of energy being released, about 3.846 x 1026 joules per second, or about 9.2 x 1010 megatons of TNT per second. Think about that: The largest H-Bomb ever detonated was around 50 megatons - The former USSR's Tsar Bomba in 1961 - Inconsequential in comparison with the Sun!

Answer 4

The Sun produces solar energy through nuclear fusion, where hydrogen atoms combine to form helium, releasing immense amounts of energy in the form of heat and light. This process occurs in the Sun's core, where the extreme heat and pressure create the conditions necessary for nuclear fusion to occur.

Answer 5

By nuclear fusion of helium. The intense gravity of the sun crushed the hydrogen atoms into helion. The energy economy of helium over two hydrogen atoms is released as heat and light.

Answer 6

Nuclear fusion reactions in the sun produce heat

Answer 7

Because of intense heat and intense pressure, protons (which are hyrogen nuclei) react together to produce helium and release energy. See the link below
