When burning helium what color is it?
orange peach color
What two gases make up 99 percent of Jupiter's atmosphere?
Hydrogen and Helium
How does the average kinetic energy of the helium atoms in a balloon change as the helium gas is heated?
the theaory of gravity when lifted by a hot air substance is qiute simple if you think about it
What is the percent composition of the gas on earth?
The atmospheric gas of Earth consists of about 78 percent nitrogen, 21 percent oxygen, 0.9 percent argon, and 0.03 percent carbon dioxide, with hydrogen, water, ozone, neon, helium, krypton, xenon, and traces of other elements making up the remaining 0.07 percent.
What are the symbols for hydrogen and helium?
The chemical symbol for helium is "He."
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 makes a star stop being a sequence star?
Basically, the stars on the "Main Sequence" are the ones that fuse hydrogen-1 into helium-4. Once a star burns up its hydrogen-1 fuel, or doesn't have much left, it will start burning helium-4 into heavier elements. It is then that the star leaves the "Main Sequence".
What is the burning point for helium?
Helium does not catch fire
What inevitably forces a star like the Sun to evolve away from being a main sequence star?
Helium builds up in the core, while the hydrogen burning shell expands.
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 happens to helium when you put a burning split in?
Nothing, helium is inert.
What are the gases burned by stars?
Stars fuse hydrogen into helium during the main sequence. After the main sequence, helium, oxygen, silicon and carbon are fused.
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.
What gases make the main sequence star?
Hydrogen and Helium
Is the sun made out of burning gasses and why?
helium is made from the sun from the atmosphere and is believed to have a percentage of 70 percent. Well, actually, helium isn't made in the sun. But even then, the atmosphere of the sun is actually made up of 54% helium to be exact. (Not far off from what you said, though.) Correction: Helium IS produced in the sun! hydrogen is fused into helium and this liberates large amounts of energy.
