What Star Expands After Exhausting Its Hydrogen Fuel?
Red Giants:)
What is the problem with hydrogen fuel cells and how can it be addressed?
The problem with hydrogen fuel cells is the high cost and limited infrastructure for producing and distributing hydrogen. This can be addressed by investing in research to lower costs, developing more efficient production methods, and expanding the hydrogen refueling network.
Water instead of gas?
Using water as a fuel source for powering vehicles is a concept called water fuel. It involves splitting water molecules into hydrogen and oxygen gas through electrolysis, then using the hydrogen as a fuel source. While promising in theory, water fuel technology is still in the experimental stages and faces challenges such as energy efficiency and infrastructure for hydrogen storage and distribution.
What is the name for the portion of a star life cycle when it is using hydrogen for fuel?
The phase of a star's life cycle where it is using hydrogen as fuel is called the main sequence phase. During this phase, a star converts hydrogen into helium through nuclear fusion in its core to produce energy and maintain its stability.
What element provides most of the fuel for stars of all sizes?
Hydrogen

What stage of life is the sun in what is its next stage?
The Sun is currently in the middle of its main sequence stage, where it has been for about 4.6 billion years, fusing hydrogen into helium in its core. It is expected to remain in this stable phase for another 5 billion years. After exhausting its hydrogen fuel, the Sun will enter the red giant phase, expanding significantly and ultimately shedding its outer layers to form a planetary nebula, leaving behind a white dwarf.
Can you use hydrogen peroxyde in a fuel cell?
Hydrogen peroxide can be used in certain types of fuel cells called direct borohydride fuel cells. In these fuel cells, hydrogen peroxide is used as an oxidant in place of oxygen. However, the efficiency and practicality of using hydrogen peroxide in fuel cells is still being researched and developed.
Why is hydrogen called a clean fuel?
Hydrogen is called a clean fuel because when it is used in fuel cells to produce energy, the only byproduct is water vapor. It does not produce greenhouse gases or air pollutants, making it an environmentally friendly and sustainable energy source.
If a star is the same mass as the sun for how many years can it fuse hydrogen and helium?
A star with the same mass as the Sun can fuse hydrogen in its core for about 10 billion years. After exhausting its hydrogen fuel, it will then enter the helium fusion phase, which lasts for around 100 million years. Therefore, while hydrogen fusion dominates its life, helium fusion is a much shorter process.
When do scientist estimate will the sun run out of fuel?
In about 5 billion years, it will enter a red giant phase, its outer layers expanding as the hydrogen fuel in the core is consumed and the core contracts and heats up See link for pictorial
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 is the byproduct of hydrogen fuel cell?
Water is the benefit of a hydrogen fuel cell ;)
Is Hydrogen Fuel Cells supposed to be capitalized?
No. Hydrogen fuel cell is not a title. You would only capitalize hydrogen if it was at the beginning of a sentence, as I did with this one. Otherwise, you would say 'hydrogen fuel cell'.
Stars spend most of their life span as giants?
Stars spend most of their life span in the main sequence phase, where they are fusing hydrogen into helium in their cores. After exhausting their hydrogen fuel, they will expand and cool down to become red giants before eventually evolving into white dwarfs or other stellar remnants.
Is hydrogen fuel cells fossil fuels?
no because hydrogen fuel cells are renewable
