How does helium and hydrogen produce so much energy on the sun?

∙ 12y ago
The cores of stars, such as our sun, have high enough temperatures and pressures to enable fusion of hydrogen nuclei - it is very difficult to fuse these positively charged particle together without these conditions. The mass of the nuclei before fusion is greater than the final mass of the fused particles - some of the mass is converted directly into energy through Einsteins equation E=mc2. m represents the mass, which although very small, is multiplied by the speed of light squared (c2), which is a very large number.

∙ 16y agobecause if it didn't it wouldn't be able to burn We know hydrogen in the sun because of GGGGGGGGGGGGGOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOODDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDD-eloscope.

How much hydrogen and helium is on Saturn?
About 96% hydrogen and 2% helium.
How does nuclear fusion occur in the Sun?
At this time hydrogen to helium burning. 1H + 1H --> 2H + e + ~1 MeV 2H + 2H --> 3H + 1H + ~4 MeV 2H + 3H --> 4He + n + ~17 MeV and several other side reactions. When it runs out of hydrogen, the core will begin helium burning. This is much harder to start so it requires much higher pressure and temperature. 3 4He --> 12C But this will not begin for another 6 billion years.
How does fusion differ for high mass stars and low mass stars?
Nuclear Fusion in a Giant Star involves Helium being fused into a hydrogen shell that surrounds the core, and Nuclear Fusion in a Main-Sequence star involves Hydrogen being fused into Helium to produce Energy inside of the core.
What nuclear process coverts helium and hydrogen gases from lighter to heavier elements?
The process is called fusion; hydrogen nuclei are fused together to make helium. At much higher temperatures and pressures, the helium can fuse into carbon and nitrogen and oxygen.
Why do modern spacecraft use helium instead of hydrogen?
Helium is much safer, so it is often used in balloons and blimps, not spacecraft.Hydrogen is still used as a fuel. Helium will not burn.
How much energy is released when one gram of hydrogen fuses into helium?

What is the process that occurs in the Sun's core to produce so much energy?
Answer 1 The process that occurs in the Sun's core to produce so much energy is called nuclear fusion. Inside the Sun the temperature and pressure gets so high that substances fuse to from new substances. This process produces a large amount of heat, light and energy. Answer 2 Fusion. Isotopes of hydrogen bond together to form helium nuclei. Helium is a bit lighter than the hydrogen isotopes from which it is formed, and this difference, known as the mass defect, is matter converted into energy.
How much hydrogen helium is on Saturn?
About 96% is hydrogen, about 3% helium.
How much hydrogen and helium is on Saturn?
About 96% hydrogen and 2% helium.
What reaction creates much of the energy given off by the sun?
Hydrogen fusion. The hydrogen atoms in the core of the sun are under such intense pressure that they combine to form helium and energy.
How do stars produce huge amounts of energy?
Stars produce so much energy because of nuclear reactions occuring in their core. Hydrogen atoms are smashing together and fusing into helium through a process known as nuclear fusion which releases huge amounts of energy.
What obstacles are there to using helium 3 as a viable energy soucre?
Helium 3 is stable. So no net energy is available from it. And there is not much of it at ground level, having been the decay product of hydrogen 3 (aka. tritium).
What are the two main elements of the sun?
Hydrogen and Helium. Also comprised of a core of much heavier elements, all the elements in the universe heavier than hydrogen probably came from supernovae.
How much Hydrogen and Helium gases is on Saturn?
kaboom
What is the main difference between a star and a planet?
Stars are luminous bodies made up of Hydrogen and some Helium which are so large the gravitational attraction has pushed the Hydrogen atoms so close together that they fuse into Helium converting a lot of mass into energy. Planets are not as big, some are rocky some gaseous.
