Main sequence stars, including our Sun, primarily burn hydrogen as fuel through the process of nuclear fusion. During this phase, hydrogen nuclei fuse to form helium, releasing energy that powers the star and produces light and heat. This process continues for billions of years until the hydrogen in the star's core is depleted. Afterward, the star may evolve into different types depending on its mass.
What else can I help you with?
Which is the element that the sun burns as fuel?
The sun burns hydrogen as fuel through a process called nuclear fusion. This process involves the fusion of hydrogen atoms to create helium, releasing energy in the form of light and heat.
How much fuel does a space shuttle burn to make it to outer space?
The Solid Rocket Boosters each burn 1,100,000 lbs of fuel. The main tank which contains essentially a liquid oxygen/hydrogen mix burns a little less than 1,200,000 lbs. A little is reserved for maneouvring in space.
What forces cause the expansion of the sun as it burns off its fuel?
The expansion of the Sun as it burns off its fuel is primarily driven by the balance between gravitational forces and the pressure generated by nuclear fusion in its core. As hydrogen is converted into helium through fusion, energy is released, creating outward pressure that counteracts gravitational collapse. Over time, as the hydrogen fuel diminishes, the core contracts and heats up, leading to increased fusion rates and causing the outer layers to expand. This process results in the Sun eventually becoming a red giant as it exhausts its hydrogen supply.
Why does the sun always burn and not go out?
The sun burns continuously due to nuclear fusion in its core, where hydrogen atoms fuse to form helium, releasing a huge amount of energy in the process. This process produces the heat and light that we receive from the sun. As long as there is enough hydrogen fuel in the sun's core, it will continue to burn and emit energy.
What is orange object on space shuttle?
The orange object on the space shuttle is the external fuel tank. It contains the liquid hydrogen and liquid oxygen that are needed to fuel the shuttle's main engines during launch. Once the fuel is consumed, the tank is jettisoned and burns up in the atmosphere.
What happens when a star burns all of its hydrogen?
When a star burns up all of its hydrogen,it becomes red in color.As hydrogen is the fuel for star and it will burst after it.
Can you name a fuel which burns without giving water vapour?
coal is a fossil fuel that burns without giving water vapour.
Why is hydrogen used as a fuel?
Hydrogen is abundant and, burns giving off only Water Vapor.
Does hydrogen cause pollution when it burns?
When hydrogen burns, the only byproduct is water vapor. Therefore, hydrogen combustion does not produce any pollution or harmful emissions. This makes hydrogen a clean and environmentally friendly fuel source.
Which is the element that the sun burns as fuel?
The sun burns hydrogen as fuel through a process called nuclear fusion. This process involves the fusion of hydrogen atoms to create helium, releasing energy in the form of light and heat.
What fuel burns in a main sequence star?
Hydrogen "burns" as it were, in "nuclear fusion" reactions to give helium and release energy.
Are stars with the most hydrogen for nuclear fuel have the longest lives?
No, stars with the most hydrogen have the shortest lives. The more massive a star is, the faster it burns its fuel, and the sooner the core is depleted.
What substance yields no toxic compounds but only water and heat when it burns?
Hydrogen (H2) is an example of a substance that yields only water and heat when it burns. When hydrogen burns in the presence of oxygen, it combines to form water (H2O) as the only byproduct, making it a clean and efficient fuel source.
Which is the fuel used in rocket engines?
It is hydrogen and oxygen, these two gases are mainly used in rockets
What element is sun burning for fuel?
Hydrogen, but its not burning, its fusing.
Is fuel a combustable?
Yes. Any thing that combusts (burns) can be used as a fuel (some examples are: wood, coal, oil, gas, hydrogen, food, etc)
What process is no longer in balance as the sun's fuel burns away?
hydrogen
