The process is called "nuclear fusion". When temperature and pressure are
high enough, the nuclei (nucleusses) of two hydrogen atoms may be forced
together so hard that they join and form a single nucleus.
Each hydrogen nucleus consists of one proton, so when they join, their combination
consists of two protons, and that's one form of the nucleus of a helium atom.
The thing that makes it more interesting is that the mass of the new nucleus is
less than the sum of the two that got squashed together to make it, and we
have to ask what happened to the missing mass. The answer is that it became
energy, and radiated away from the spot where the two nuclei were joining.
That's the process responsible for the energy that radiates from the sun, and
from most stars during most of their life.
Scientists and engineers have developed the technology to be able to create
nuclear fusion here on Earth, although it's still somewhat messy. You'd think
that this is a pretty good way to generate energy for our use, and you're
absolutely right. The problem is that when fusion is going on and energy is
coming out, it's so hot that nothing has been developed yet to keep it in. So
right now, there's only one device that regularly uses nuclear fusion here on
Earth. We call that device the "hydrogen bomb".
What else can I help you with?
What is the main activity of a sequence star?
The activity is -fusing hydrogen into helium.
In stars hydrogen nuclei combine with each other to form helium and other heavier elements. What is this process called?
This process is called "nuclear fusion".
What is the main source of energy in star like sun?
Hydrogen fusion is the main energy source in any star.Put very simply, four Hydrogen atoms fuse to create Helium. The atomic weight of Helium is slightly less than four Hydrogen atoms the extra mass is released as energy.
Do stars give off light as a part of a nuclear fusion reaction in which helium atoms are split into hydrogen atoms?
No. In a fusion reaction, a heavier element is made of a lighter pair by "gluing" them together in a fusion reaction. When we split an atom, that's called atom splitting, or sometimes fission, not fusion. They are opposites. Stars give off light, but the primary fuel in their fusion engines is hydrogen, which they convert into helium. As the hydrogen burns out, the star begins making helium into carbon.
What is the star Sirius a made of?
most stars are made of mainly hydrogen, a little helium and traces of other gases like oxygen
How is helium which is produced by the conversion of hydrogen into energy related to the solar core?
Helium is produced in the solar core through nuclear fusion reactions, which convert hydrogen into helium, releasing enormous amounts of energy. This process is crucial for the sun to maintain its energy output and support life on Earth.
Which process does the Sun use to produce energy?
The conversion of Hydrogen into Helium (nuclear fusion).
Why does the amount of hydrogen in a star decrease over time?
The amount of hydrogen in a star decreases over time because the star fuses hydrogen into helium in its core through the process of nuclear fusion. This conversion of hydrogen into helium releases energy that powers the star and results in a gradual depletion of its hydrogen fuel source.
Is it true that gassing is the conversion of the battery water into helium and nitrogen gas?
No, the battery generates hydrogen gas. This can be explosive!
What nuclei bond together during the solar nuclear reaction?
During the solar nuclear reaction, hydrogen nuclei (protons) bond together to form helium nuclei through a process called nuclear fusion. This fusion involves the conversion of hydrogen into helium, releasing a large amount of energy in the form of light and heat.
What are the symbols for hydrogen and helium?
The symbol for hydrogen is H, and the symbol for helium is He.
Why is energy produced by the sun when hydrogen fuses into helium?
Energy is produced in the sun when hydrogen fuses into helium through a process called nuclear fusion. This process releases a huge amount of energy in the form of light and heat due to the conversion of mass into energy according to Einstein's famous equation, E=mc^2.
What are the two main elements found in the stars?
Hydrogen and helium
Hydrogen and helium formulas?
Hydrogen is H2. Helium is He.
How is helium formed from hydrogen?
It's called the proton-proton cycle. It's the source of the sun's energy. Also called nuclear fusion.
What is it called when particles of hydrogen smash into each other and form helium?
It is called Hydrogenica
When different isotopes of hydrogen fuse in the sun nuclei of what are produced?
When different isotopes of hydrogen fuse in the sun, they produce helium nuclei. Specifically, the fusion process in the sun involves the conversion of hydrogen isotopes, such as deuterium and tritium, into helium-4 nuclei, along with the release of energy in the form of gamma rays and solar radiation.
