What will happen to the relative amounts of hydrogen and helium in the sun over the next few billion years?
Over the next few billion years, the hydrogen content in the sun will decrease as it fuses into helium through nuclear fusion. This process will cause the relative amount of helium to increase in the sun over time.
How long can a star like your Sun produce energy through fusion of hydrogen to helium?
A star like the sun has about enough hydrogen to burn on the main sequence for about 12 billion years. Our sun has been burning for about 6 billion, so we have about 6 billion more before it switches to helium -> carbon burning, becomes a red giant and consumes all the inner planets out to and including earth.
What will happen to the amounts of hydrogen and helium in the sun over the next billion years?
Over the next billion years, the amount of helium in the Sun will increase as hydrogen is fused into helium in the core through nuclear fusion. This process will cause the Sun to gradually expand into a red giant, using up its hydrogen fuel. After that, it may start fusing helium into heavier elements, while shedding its outer layers into space.
What is our sun fueled by?
Our Sun, as with all main-sequence stars, is heated by the energy of fusing hydrogen atom to make helium atoms. The gigantic gravity of a main-sequence star causes hydrogen atoms to be smashed together, or 'fused'. The huge heat that results keeps the Sun puffed up to its huge size. In another 4.5 billion years, more or less, the hydrogen will be largely used up, and the Sun will shrink to a point that helium atoms are smashed together, creating lithium atoms. When all the lithium atoms have been largely smashed together and used up, the Sun will shrink again, and beryllium atoms will result.
Where is your sun in its life cycle?
The sun is in its middle age. Its around 5 billion years old, and will keep fusing hydrogen into helium for another 5 billion years. In about 5 billion years the sun's core will run out of Hydrogen and begin fusing helium into carbon. At this point the sun will balloon outwards become 1 to 10 times its current size but the surface temperature will lower because it is further from the core. It will turn red in color and eventually after it has fused all the helium into carbon it will release its out layers into what is known as a planetary nebula and nothing will be left but the white hot core known as a white dwarf star.
What is nuclear fusion in the Sun?
This is the fusing of hydrogen atoms to form helium atoms, and in some cases heavier elements as well. The dominant reaction in our Sun is the combining of hydrogen isotope atoms to form helium atoms. Deuterium atoms, which are hydrogen atoms which have a neutron, are forced together to form a helium atom, which is two protons and two neutrons, and some energy is produced. The Sun is slowing using up its supply of hydrogen, but there is enough to last for at least another two or three billion years.
What were the gases in the air 4.5 billion years ago?
4.5 billion years ago the earth was a molten ball surrounded by hydrogen and helium.
Will thew sun burn out?
The sun is using up its supply of hydrogen because the hydrogen atoms are being converted into helium atoms. Only seven tenths of one percent of the available hydrogen actually converts into heat energy, and the best estimate is that it will take another one hundred billion years for all the hydrogen to be used up. So, at the end of one hundred billion years, the sun will, in fact, burn out.
Where were helium and and hydrogen formed?
Hydrogen was initially formed in the 'Big Bang' which initiated this universe. Helium is formed by the fusion of hydrogen atoms, inside stars. This reaction is what causes stars to shine, and give off heat.
What will happen to the relative amounts of hydrogen and helium in the sun over the next few billion years?
Over the next few billion years, the hydrogen content in the sun will decrease as it fuses into helium through nuclear fusion. This process will cause the relative amount of helium to increase in the sun over time.
Which stage of stellar evolution is characterized by the fusion of hydrogen atoms into helium atoms?
The stage of stellar evolution characterized by the fusion of hydrogen atoms into helium atoms is known as the main sequence phase. During this phase, a star generates energy through nuclear fusion in its core, balancing the gravitational forces pulling inward with the outward pressure from the fusion reactions. This stage can last billions of years, depending on the star's mass. The Sun, for example, has been in the main sequence stage for about 4.6 billion years and is expected to remain in this phase for several billion more.
Why will the sun burn out?
The sun generates energy by fusing hydrogen into helium. Eventually it will run out of hydrogen. However, this won't happen for several billion years.
How will the sun burn out?
In a sense. The sun produces energy by fusing hydrogen into helium in its core. In about 5 billion years that hydrogen will burn out. Over the following two billion years the sun will fuse helium in the core and hydrogen in a surrounding shell before shedding its outer remnants and leaving behind a degenerate remnant called a white dwarf.
How long can a star like your Sun produce energy through fusion of hydrogen to helium?
A star like the sun has about enough hydrogen to burn on the main sequence for about 12 billion years. Our sun has been burning for about 6 billion, so we have about 6 billion more before it switches to helium -> carbon burning, becomes a red giant and consumes all the inner planets out to and including earth.
What will happen to the amounts of hydrogen and helium in the sun over the next billion years?
Over the next billion years, the amount of helium in the Sun will increase as hydrogen is fused into helium in the core through nuclear fusion. This process will cause the Sun to gradually expand into a red giant, using up its hydrogen fuel. After that, it may start fusing helium into heavier elements, while shedding its outer layers into space.
When would the sun go out?
When the Helium, morphing into hydrogen and causing nuclear reactions runs out. So appoximately 5 billion years.
Where has the process of nuclear fusion been occurring for over four billion years?
Nuclear fusion has been occurring in the core of the Sun for over four billion years. The intense heat and pressure at the Sun's core allow hydrogen atoms to fuse into helium, releasing a tremendous amount of energy in the process.
