Rate of conversion of hydrogen to helium in the sun
The proton–proton chain reaction is one of two known sets of nuclear fusion reactions by which stars convert hydrogen to helium.It dominates in stars with masses less than or equal to that of the Sun, whereas the CNO cycle, the other known reaction, is suggested by theoretical models to dominate in stars with masses greater than about 1.3 times that of the Sun. As shown above, the conversion of hydrogen to helium, by reducing the hydrogen density d H, should reduce the energy production in the core. But this cannot happen, because the star will only remain stable if the energy production in the core is the same as the rate of heat loss at its surface. How does the sun convert hydrogen into helium? Answer Save. 10 Answers. Relevance. mathematician. Lv 7. 1 decade ago. Favorite Answer. The sun uses a series of nuclear reactions called the hydrogen cycle. First, two protons hit each other and one is converted into a neutron and a positron. The proton and neutron cling together to make a The Hydrogen Fusion Process In the basic Hydrogen fusion cycle, four Hydrogen nuclei (protons) come together to make a Helium nucleus. neutrinos and photons involved that make the fusion of Hydrogen into Helium possible. It is another name for the Sun's magnetic field. The Sun's magnetic field is huge! It goes beyond any of the planets. Yet the Sun is so large that it has been burning hydrogen at this rate ever since it formed some 5 billion years ago, and it will continue to burn steadily for at least another 4 billion years. The energy released by nuclear fusion in the heart of the Sun is eventually radiated away in all directions into space. Nuclear Fusion in the Sun Explained Perfectly by Science. Nuclear fusion is the source of Sun's phenomenal energy output. The Hydrogen and Helium atoms that constitute Sun, combine in a heavy amount every second to generate a stable and a nearly inexhaustible source of energy.
As the helium "ashes" continue to pile up at its center, a higher fraction of them the helium-burning and hydrogen-burning shells don't burn at the same rate.
How many Kg of Hydrogen does the sun convert into Helium per year? Now my main problem is that I don't have the rate of conversion. I know 21 Sep 2016 The discovery that the sun is made mostly of hydrogen and helium was pair of helium atoms, and in that process the mass that is lost is converted the radiation from this process at the current rate will allow the sun to burn 14 Dec 2015 The sun releases energy at a mass–energy conversion rate of 4.26 Basically, this involves ions of hydrogen and helium emitting photons that 12 Feb 2015 In a few billion years, the sun will become a red giant so large that it will engulf our planet. part of its life, converting the hydrogen present in its core into helium. After 8 billion years of happily burning hydrogen into helium are over, Where the models differ is on the speed with which the earth reaches
For main-sequence stars with elemental abundances similar to the Sun, the conversion of hydrogen into helium is equal for the two processes when a star is about 2 solar masses. Below about 1.2 solar masses, the contribution to the energy production from the CNO process is insignificant; this means that the Sun is powered only by the PP process.
At the center of the Sun is its core, where nuclear fusion generates energy by the nuclei of several hydrogen atoms to fuse together to form helium atoms. Einstein's famous equation, E = mc2, in which c, the speed of light, is a very, very big number! In each type of nuclear reaction, some matter is converted into energy. of hydrogen, helium, and metal nuclei, plus electrons from each species: Number …even rotation rates much faster than the Sun ought to be negligibly small large luminosity, can convert this into an expression for the maximum luminosity.
How many Kg of Hydrogen does the sun convert into Helium per year? Now my main problem is that I don't have the rate of conversion. I know that each 4 protons (H atoms) for one Helium atom, but at what rate?
But the new helium atom weighs slightly less than two hydrogen atoms, so the Therefore supergiant stars burn through their hydrogen at a faster rate and shine a typical star like the Sun will convert about 10% of its hydrogen into helium. How many Kg of Hydrogen does the sun convert into Helium per year? Now my main problem is that I don't have the rate of conversion. I know 21 Sep 2016 The discovery that the sun is made mostly of hydrogen and helium was pair of helium atoms, and in that process the mass that is lost is converted the radiation from this process at the current rate will allow the sun to burn 14 Dec 2015 The sun releases energy at a mass–energy conversion rate of 4.26 Basically, this involves ions of hydrogen and helium emitting photons that 12 Feb 2015 In a few billion years, the sun will become a red giant so large that it will engulf our planet. part of its life, converting the hydrogen present in its core into helium. After 8 billion years of happily burning hydrogen into helium are over, Where the models differ is on the speed with which the earth reaches 16 Apr 2014 Nuclear fusion already takes place in the sun's core, after all. when intense pressure and heat fuse hydrogen atoms together, generating helium and energy. C is a constant number that is the speed of light in a vacuum.)
30 May 2010 This conversion also releases two tinier particles — a positron and a lightweight, The sun takes four hydrogen atoms and forges the element helium during the fusion process at the rate of four million tons per second.
Luminosity = how much energy the Sun releases each second. So… Sun's lifetime million degrees. The conditions are right for fusing hydrogen into helium. The Sun's core The rate at which extra mass was converted to energy: a lot of it.
The sun generates energy in its core in a process called nuclear fusion. Four hydrogen nuclei fuse to become one helium atom. The solar energy travels to the earth at a speed of 186,000 miles per second, the Solar-powered calculators, toys, and telephone call boxes all, use solar cells to convert light into electricity. In this stage four hydrogen nuclei (protons) are fused to create a helium it could mimic the entry of a solar neutrino by converting an atom of chlorine 37 (37Cl) It proceeds at a rate of about once for every 1,000 occurrences in the sun of the
