The percentage of oxygen in air is 21%.
Gas particles in the air contribute to air pressure. The molecules constantly collide with each other and with surfaces, exerting a force per unit area, which we perceive as pressure. The more gas particles present in a given space, the higher the air pressure will be.
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.
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.
it is not gas it is just air
Gas rich refers to a substance or environment that contains a high proportion of gas compared to other components. It often implies that the gas content is significant or predominant in the given context.
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.
Air contains about 21% oxygen and 78% nitrogen, while water can only dissolve a limited amount of gas. Therefore, the oxygen in air dissolves in water at a higher proportion than nitrogen. This is due to the partial pressure of oxygen being higher in air compared to nitrogen.
For each gas exist a specific test; a general method is based on the infrared spectrometry.

A gas burner in a gas-fired furnace mixes air and gas to create a combustible mixture. The burner nozzle releases gas, which mixes with air that is drawn in from the surrounding environment. This mixture is then ignited to produce heat for the furnace.
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.
To present a pie chart showing the gases in air, you can divide the chart into sections representing the percentage of each gas in the air composition. Label each section with the name of the gas and its corresponding percentage. Displaying the relative sizes of the sections will visually represent the composition of gases in air.

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.
