How does the proton-proton chain produce energy?

The process is called the Proton-Proton (PP) Chain, and it operates inside the Sun and stars of similar mass. So what did we do? 1 positron (this positron will bump into a electron and annihilate, creating a gamma ray – energy!).

Why does the proton-proton chain produce energy that powers the sun?

The proton-proton chain. This is the principle fusion reaction in the Sun. photons In the proton-proton chain reaction, hydrogen nuclei are converted to helium nuclei through a number of intermediates. The reactions produce high-energy photons (gamma rays) that move through the “radiative layer” surrounding the core.

What are the products of the proton-proton chain?

Main branch of the proton-proton chain.

  • Two mass-1 isotopes of hydrogen undergo a simultaneous fusion and beta decay to produce a positron, a neutrino, and a mass-2 isotope of hydrogen (deuterium).
  • The deuterium reacts with another mass-1 isotope of hydrogen to produce Helium-3 and a gamma-ray.

What is proton-proton chain process?

The proton–proton chain, also commonly referred to as the p-p chain, is one of two known sets of nuclear fusion reactions by which stars convert hydrogen to helium. The proton-proton chain is, like a decay chain, a series of reactions. The product of one reaction is the starting material of the next reaction.

Which is the final result of the proton-proton chain?

The final result is a normal helium-4 nucleus and two protons. From this process 98% of the energy released comes out as kinetic energy of the resulting helium nuclei and radiative energy of the gamma rays.

What is the net result of the proton-proton chain?

The net result of this chain is the fusion of four protons into a single ordinary helium nucleus (4He) with energy being released to the star in accordance with Einstein’s equation. Particles called ‘neutrinos’ ( ) are emitted in these fusion processes.

How many nuclear reactions occur in a proton-proton chain?

five reactions

What happens to the neutrinos that are produced in the proton-proton chain quizlet?

What happens to the neutrinos that are produced in the proton-proton chain? They head out of the sun at nearly the speed of light.

Why couldn’t you stand on the sun’s surface?

Why couldn’t you stand on the Sun’s surface? A. The Sun’s surface is too highly magnetized for anything to survive there.

Which part of the sun’s atmosphere is the hottest?
