## Rate of conversion of hydrogen to helium in the sun

sun is made up mostly of hydrogen and helium atoms in a plasma state. The sun speed of 186,000 miles per second, the speed of light. The conversion of.

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. 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. Most stars derive their luminosity from the conversion of hydrogen to helium. About 0.4% of pp reactions in the Sun start with 2p + e− → 2H + νe instead of the 4.6 Gyr since its formation; thus the fusion rate per proton is ≈ 5×10−18 s−1. constant rate and after that hour you notice the gas If you continue at this rate, what is the total possible the Sun: 71% Hydrogen, 27% Helium and 2%. Today, the Sun continues to fuse hydrogen atoms to make helium in its core. million tons of hydrogen are converted to energy, which makes the Sun shine.

## Inside the Atom. Let's look at Hydrogen and Helium (98% of the Sun) Mass and energy are equivalent, related by the speed of light, c. So we can also talk about The Sun can only convert the inner 10% into helium. How much energy is

Since stars spend roughly 90% of their lives burning hydrogen into helium on the fusion reactions in these stars proceed at a faster rate than in lower mass stars. The Sun, a G-type star with a main sequence lifetime of ~ 10 billion years, The mass converted into energy through burning will be a fraction f of the total  30 Jan 2016 Helium-3 (He3) is gas that has the potential to be used as a fuel in future In current nuclear fusion reactors, the hydrogen isotopes tritium and use of the same energy source that fuels the Sun and other stars, and does not  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. It might surprise you to learn that hydrogen-fusing-into-helium makes up less than half of all nuclear reactions in our Sun and that it's also responsible for less than half of the energy that the 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? The Sun is at least 90 percent hydrogen by number of atoms, so the fuel is readily available. Since one hydrogen atom weighs 1.0078 atomic mass units and a single helium atom weighs 4.0026, the conversion of four hydrogen atoms to one helium atom yields 0.0294 mass unit, which are all converted to energy, 6.8 million electron volts (MeV, 1 MeV = 1.6 × 10 −6 erg), in the form of gamma (γ) rays or the kinetic energy of the products. For abundances characteristic of the Sun, the CNO process becomes important for core temperatures of roughly 15 million degrees (1.3 keV), and it provides virtually all of the conversion of hydrogen into helium above 25 million degrees (2.2 keV).

### In each nuclear conversion 4 hydrogen atoms are combined to produce a helium atom. This reaction occurs throughout the Sun and by this process our Sun

### 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.

Sun – The Ultimate Nuclear Fusion Reactor. Every second, the Sun fuses 620 billion Kg of Hydrogen nuclei (protons) into Helium, to produce 384.6 trillion trillion Joules of energy per second. This is equivalent to the energy released in the explosion of 91.92 billion megatons of TNT per second.

Discussion of changes in the Sun's structure and energy production toward the end of its Main Hydrogen is turned to helium at a rate proportional to the rate of fusion. As shown above, the conversion of hydrogen to helium, by reducing the   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  Since stars spend roughly 90% of their lives burning hydrogen into helium on the fusion reactions in these stars proceed at a faster rate than in lower mass stars.
