What fraction of the atmosphere's mass is below an aircraft flying at the 700 mb level?
The 700 mb level of the atmosphere is 10,000 feet in the air. This level is the second level used for measuring the atmosphere in the troposphere, so 1/5 of the atmosphere is located below it.
If the spectrum of a star shows the same absorption lines as the sun what can be said about the stars composition?
When stars form in the present Milky Way galaxy they are composed of about 71% hydrogen and 27% helium,[87] as measured by mass, with a small fraction of heavier elements. Typically the portion of heavy elements is measured in terms of the iron content of the stellar atmosphere, as iron is a common element and its absorption lines are relatively easy to measure. Because the molecular clouds where stars form are steadily enriched by heavier elements from supernovae explosions, a measurement of the chemical composition of a star can be used to infer its age.[88] The portion of heavier elements may also be an indicator of the likelihood that the star has a planetary system.[89] The star with the lowest iron content ever measured is the dwarf HE1327-2326, with only 1/200,000th the iron content of the Sun.[90] By contrast, the super-metal-rich star μ Leonis has nearly double the abundance of iron as the Sun, while the planet-bearing star 14 Herculis has nearly triple the iron.[91] There also exist chemically peculiar stars that show unusual abundances of certain elements in their spectrum; especially chromium and rare earth elements Edit : That's interesting, but it doesn't answer the question. The answer is that the star and the Sun must have the same chemical elements in their "atmospheres".
Is the moon very hot?
No, the moon is quite cold. Unlike the earth and other large planets, the moon's gravity is just a fraction of earth's and so it is not strong enough to retain an atmosphere. So, without an atmosphere, the surface of the moon is no different from deep space... with a floor. Heat energy radiates out into space and dissipates. Thus, the ambient temperature approaches absolute zero.
What causes meteorites to burn up?
Meteors do not burn up in space. They burn up in the atmosphere, because of the intense heat caused by their speed through the air. A recently observed meteor - one of this year's Perseid meteors - was measured at 130,000 miles per hour. Given that speed, it isn't surprising that it melts to plasma within a fraction of a second.
What amount of oxygen is on Mars?
While we would find it pretty thin breathing (and poisonous, to boot!) Mars does have an atmosphere, and there IS some oxygen in it.At its densest, Mars's atmosphere is only about 1% the density of Earth's and consists mainly of carbon dioxide (95%) and nitrogen (3%), with trace amounts of water, oxygen, hydrogen peroxide and methane having also been identified.Earth's atmosphere, on the other hand, is mostly nitrogen (78%) and oxygen (21%) with 1% being a mix of hydrogen, carbon dioxide and others.So you can see that Mars has much less atmosphere than the Earth does and oxygen make a proportionally much smaller fraction of of what there is than what we have on Earth.
What is the mass percent composition of an element in a molecule?
Percentage composition= (mass of the element/mass of the molecule)*100 The fraction of the molecule's mass that comes from the element's mass
What fraction of all arrests do misdemeanors comprise of?
The question is not sufficiently specific. Where and over what period?
Which layer of the atmosphere contains only a tiny fraction of the atmosphere's mass?
Ozone layer is the layer. It contains tiny fraction of atmospheric mass.
Why does the petrol fraction have a lower viscosity than the fuel oil fraction?
The viscosity depends on the chemical composition of materials.
What fraction of the grand canyon is dessert?
Well the chocolate valley and whipped cream hills comprise about 53 percent...
What fraction of your atmosphere is Oxygen gas?
About 1/5
What is a unit rate in fraction?
It is a fraction in which one of the elements - usually the numerator - is 1.
What is Saturn's composition?
Saturn's composition is mostly hydrogen, helium, and hydrogens compounds. The outer atmosphere consists of about 96.3% molecular hydrogen and 3.25% helium. Trace amounts of ammonia, acetylene, ethane, phosphine, and methane have also been detected. The upper clouds on Saturn are composed of ammonia crystals, while the lower level clouds appear to be composed of either ammonium hydrosulfide (NH4SH) or water. The atmosphere of Saturn is significantly deficient in helium relative to the abundance of the elements in the Sun. The quantity of elements heavier than helium are not known precisely, but the proportions are assumed to match the primordial abundances from the formation of the Solar System. The total mass of these elements is estimated to be 19-31 times the mass of the Earth, with a significant fraction located in Saturn's core region.
What is the composition for copper?
Compostion Fraction by weight 1,000000 Atomic number 29.
What is the structure and composition of the atmosphere?
A thin layer of gases covering the Earth, more than half less than 5 miles from the surface, but with wisps going up to about 1000 miles (or more). The composition (near the surface) is 79 % nitrogen, 20% oxygen, and 1% argon. There is also a tiny fraction of water vapor, CO2, and methane.
What fraction of the atmosphere consists of water vapor?
1/3
What fraction of water resides in the Earth's Atmosphere?
The amount of water in the earth's atmosphere is 1/3000.
