When burning helium what color is it?
When helium is burned, it produces a faint blue color. This is due to the electronic transitions that occur in the helium atoms during the combustion process.
What two gases make up 99 percent of Jupiter's atmosphere?
Hydrogen and helium make up 99 percent of Jupiter's atmosphere. These two gases are the most abundant elements in the planet's composition.
How does the average kinetic energy of the helium atoms in a balloon change as the helium gas is heated?
As the helium gas in a balloon is heated, the average kinetic energy of the helium atoms increases. This is because an increase in temperature leads to higher molecular speeds and greater kinetic energy for the gas particles. The particles move faster, resulting in more collisions and increased kinetic energy.
What is the simble for helium?
The symbol of Helium is He. Helium's atomic number is 2.
What is helium flash?
A helium flash occurs because the core of the star is in what is known as a "degenerate" state. This means that the core has contracted so much that the pressure of the electron shells of the atoms making up the core prevent the core from contracting further. Under normal gas conditions (i.e. NOT a degenerate state), an increase in the temperature of the core would cause an increase in core pressure resulting in the core expanding and the temperature then dropping. This state is known as hydrostatic equilibrium. With a degenerate core, the temperature increases but the pressure doesn't. This extra energy ignites the helium creating run-away nuclear reactions. This is what is referred to as a "helium flash."
What ful do stars on the main sequence burn?
it is fusion of hydrogen into helium. (like our sun) if it is a red giant (the next stage of our suns life) it is burning helium into denser things.
Is a red giant a main sequence star?
No, a red giant is a star that has just left the hydrogen burning main sequence and begun the next step, burning helium. As helium undergoes fusion at a much higher temperature than hydrogen undergoes fusion, the star expands dramatically and as it expands its outer layers cool to red heat.
What is the classification of about 90 percent of the stars?
About 90 percent of stars are classified as main sequence stars, which means they are in the stable phase of their lifecycle where they are fusing hydrogen into helium in their cores. These stars follow a pattern on the Hertzsprung-Russell diagram known as the main sequence.
About 90 percent of the stars including the sun are what stars?
About 90 percent of the stars, including the sun, are main sequence stars. This means they are in a stable phase of their life cycle, converting hydrogen into helium through nuclear fusion in their cores.
What happens to helium when you put a burning split in?
Nothing, helium is inert.
What is the process of thermonuclear fusion in a helium-burning star?
3 He fuse to 1 C. Note you HAVE to skip Beryllium in the fusion sequence, it won't let you get by it if you try going through it.
What stage will the sun enter next?
The sun is currently in the main sequence stage. Next, it will evolve into a red giant as it depletes its hydrogen fuel and starts burning helium in its core.
90 percent of the stars including your sun are what stars?
90 percent of stars, including the Sun, are main sequence stars. These stars are in a stable phase of nuclear fusion, converting hydrogen into helium in their cores to produce energy. Main sequence stars like our Sun are the most common type of stars in the universe.
Where does a star spend most of its lifetime on an h r diagram?
MAIN-SEQUENCE The average star spends 90% of its life as a hydrogen burning MS star.
Classification of about 90 percent of the stars?
About 90 percent of stars are classified as main sequence stars, which are stable, fusing hydrogen into helium in their cores. These stars follow a distinct relationship between their luminosity and temperature, known as the Hertzsprung-Russell diagram. Main sequence stars include our Sun and have a lifespan ranging from millions to billions of years.
What gas in the air is used for burning?
helium
What percent of hydrogen is fused to helium in the sun and what percent is fused to energy?
99.993 % into Helium, .007 % into energy.
