What else can I help you with?
Is the sun rocky or gas?
The sun is mostly made of gas (around 75% hydrogen and 24% helium), with a small rocky core at its center. The intense heat and pressure at the core create nuclear reactions that power the sun's energy.
What percent of the sun is hydrogen?
About 74% of the Sun's mass is hydrogen. This element is essential for nuclear fusion reactions that power the Sun, converting hydrogen into helium and releasing energy in the process.
Why is the sun slowly changing from being made of hydrogen to being made of Helium?
It is because of the nuclear fusion reactions which power the Sun. They produce energy by converting hydrogen into helium. In fact it's more complicated than the question suggests, but that's the basic idea.
What two gas are stars made of?
Stars are primarily made of Hydrogen gas (or Hydrogen plasma).The primary reaction in stars to produce energy is called Fusion where two Hydrogen molecules combine to produce one Helium molecule.Thus, a second common element in stars would be Helium (also usually found in plasma form).
What two gases make up more than 90 percent of the sun?
The sun is primarily composed of hydrogen and helium, which together make up more than 90 percent of its mass. Hydrogen accounts for about 74 percent, while helium makes up approximately 24 percent. These two gases are crucial for the nuclear fusion processes that power the sun.
What is the difference in lifting power between hydrogen and helium?
Hydrogen has more lifting power than helium because it is lighter. This means that a given volume of hydrogen can lift more weight than the same volume of helium.
Nuclear fusion on the sun changes hydrogen into?
Nuclear fusion on the sun changes hydrogen into helium. This process releases energy in the form of light and heat. It is the source of the sun's power and the reason for its brightness and warmth.
Hydrogen plus hydrogen helium?
When two hydrogen atoms react, they can combine to form helium through nuclear fusion. This process releases a tremendous amount of energy and is the basis for the power source of the sun and other stars.
Will helium 3 allow us to use nuclear fusion for power?
On earth, for power production, the most likely fuel source will be hydrogen isotopes, not helium 3
What is the role of hydrogen and helium in the sythesis of elements?
Hydrogen and helium are the most abundant elements in the universe. And stars use them for power. To put it simply, hydrogen is fused into helium, and helium into carbon. All the heavier elements are made from there up through iron. The trans-iron elements are made is a supernova. It could be argued that hydrogen and helium are the basic building blocks of other elements.
What happens when hydrogen is converted to helium?
When hydrogen is converted to helium through nuclear fusion, a large amount of energy is released. This process is the main source of energy in stars like our Sun. It involves the fusion of hydrogen nuclei (protons) to form helium nuclei, releasing photons and neutrinos in the process.
How does a main sequence star power itself?
A main sequence star gets its energy by fusing hydrogen-1 into helium-4.
What element is created when hydrogen atoms fuse together in the sun and core?
When hydrogen atoms fuse together in the sun's core, they create helium. This process releases energy in the form of light and heat, which provides the sun's power.
What natural gases give power to the sun?
Our sun gets energy from fusing hydrogen atoms with neutrons to form helium atoms.
Is the sun rocky or gas?
The sun is mostly made of gas (around 75% hydrogen and 24% helium), with a small rocky core at its center. The intense heat and pressure at the core create nuclear reactions that power the sun's energy.
What percent of the sun is hydrogen?
About 74% of the Sun's mass is hydrogen. This element is essential for nuclear fusion reactions that power the Sun, converting hydrogen into helium and releasing energy in the process.
How does the amount of Hydrogen differ from that of helium in the Sun mass?
The Sun is about 70% hydrogen, 28% helium, and 2% "other". When the Sun gets to about 50% hydrogen, the amount of helium present will seriously interfere with the hydrogen fusion, and the Sun will begin to collapse under its own gravity. The Sun's core is currently around 15 million degrees Kelvin. As the Sun collapses, the increasing pressure will heat the Sun, and when it gets to about 45 million degrees, the Sun will begin fusing helium and with the new power source will expand into a red giant. We expect this to happen in about 4 billion years, perhaps a little more.
