Sentences with phrase «nitrogen and oxygen»

Note, however, that the bulk of the atmosphere is made up of nitrogen and oxygen molecules which don't absorb IR at all.
An electrical charge — from lightning or a man - made source such as an electrical generator — splits atmospheric nitrogen and oxygen molecules into separate atoms.
The concentration of water vapor in the atmosphere reflects the number of molecules of water compared with the total number of air molecules (mainly nitrogen and oxygen).
Because water vapor is lighter than dry air (mostly nitrogen and oxygen), that layer of air can move upward in the attic.
The white, blue and red balls represent carbon, nitrogen and oxygen atom respectively.
Once in the atmosphere, the charged particles interact with gas particles, including nitrogen and oxygen, which triggers bursts of light.
Of course, this is also true of nitrogen and oxygen, the two primary components of air.
Yet, scattering by nitrogen and oxygen can only explain how sunsets can be orange and perhaps reddish, not how the sky can blush blood red.
training in the lab, only 5 % of her Ph.D. time was actually devoted to chemical experiments; her aim was to determine the influence of nitrogen and oxygen on the growth and etching of diamonds, which required a lot of computer - simulation studies.
The color difference occurs because Earth's auroras are dominated by excited nitrogen and oxygen molecules, and Saturn's auroras are dominated by excited hydrogen molecules.
In the study, the researchers examined nitrogen and oxygen isotopes in N2O samples collected from permafrost peatland sites in northwestern Russia.
The researchers tested a variety of solutions containing the soil bacteria Geobacter sulfurreducens and Thiobacillus denitrificans, which thrive by eating acetate (an organic compound that makes vinegar sour) and nitrate (a negatively - charged molecule of biologically available nitrogen and oxygen), respectively, when they can find a spare electron or two.
These emissions track the recombination of atomic nitrogen and oxygen produced on the dayside, and reveal the circulation patterns of the atmosphere.
The only molecules that are not transparent like nitrogen and oxygen are other Carbon Dioxide molecules.
Moreover, reactive nitrogen and oxygen species (RNOS) are used extensively in cellular signalling, and cells adaptively regulate endogenous antioxidants on short time scales to respond to deletorious spikes of RNOS faster than we could ever achieve with dietary antioxidants.
A naturally occurring mixture of gases, chiefly nitrogen and oxygen with small amounts of argoin, carbon dioxide and water vapour - we sometimes call this our atmosphere
In atmospheric physics, lidar is used as a remote detection instrument to measure densities of certain constituents of the middle and upper atmosphere, such as potassium, sodium, or molecular nitrogen and oxygen.
This process uses atoms of carbon, nitrogen and oxygen as intermediaries in the fusion process.
The composition of human flatus has been studied (Suarez et al. 1997; Tomlin et al. 1991), and comprises mostly nitrogen and oxygen (derived from air that has been swallowed or diffusion from the blood), and carbon dioxide, hydrogen, and methane (arising intraluminally from chemical reactions and bacterial fermentation).
Be it the azure of high noon or the orange glow of dusk, the colors of the sky result from sunlight interacting with molecules in the air, primarily nitrogen and oxygen, which cause it to be deflected in all directions, a phenomenon called Rayleigh scattering.
When they arrive to the nightside, the molecules go to a lower altitude and combine with nitrogen and oxygen atoms to create nitric oxide molecules.
