The percentage of oxygen in air is 21%.
The dry air contains about 78% nitrogen, 21% oxygen and remaining 1% contains noble gases . carbon dioxide and some other gases.
nitrogen - 78%
oxygen - 21%
other gases (carbon di oxide , methane) - 1%
The percentage of oxygen in air is 21%.
78% Nitrogen, 21% Oxygen, 1% trace gases
3%
If you blow it up with your mouth you make it heavier. You breathe out air containing a higher proportion of carbon dioxide than the air you breathe in. Carbon dioxide is a relatively heavy gas (nearly three times as dense as air) and so this increased amount of gas, plus the rest of the air in the balloon, will make the balloon heavier.
In a mixture of gases, for example 70% Helium and 30% Oxygen, the pressure exerted will be split 70/30 between the gases, respectively. As John Dalton discovered, the proportion of these pressures is the proportion of the number of molecules of the gas within the mixture.
it is not gas it is just air
Air. (Oxygen, Carbon Dioxide)
Yes Argon is a gas in dry air
Ozone's proportion is very low in the atmosphere. It is a rare gas.
It is so because the gases are not chemically bonded to each other and are present in any proportion to each other.
The diagram shows four gas-jars. Each contains a different gas. Burning magnesium is put into each jar. air,exhailed air, nitrogen, oxagen
The adjustable air inlet at the end of each of the burner tubes near the fuel nozzle.
For each gas exist a specific test; a general method is based on the infrared spectrometry.

when you cross multiply you get the same number for each side its an equal proportion
A proportion says that two ratios are equal. In other words, it is an equation in which each side is a fraction.
In direct proportion to the air currents
Air insulated means the substation is in the open air, and the dielectric strength of the air is used to isolate conductors from each other and from ground. Gas insulated means a specific gas is used for insulation; this gas is usually an inert gas such as nitrogen. Gas insulated substations, by definition, are required to be inside a contained structure, or large piping must be placed around all conductors to hold the gas.
