Many gases can facilitate buoyancy. The most used today are helium and hot atmospheric gasses.
Gas. The Earth's atmosphere is composed of gases that make up the air we breathe.
Argon is an inert gas and does not react with other elements, so it has no direct effect on the air around us. However, it is commonly used in various applications such as welding and lighting, where it can displace oxygen to create a stable environment.
Helium rises because it is less dense than the air. If it is less dense then it will rise above the air until it meets a gas lighter than it. There are other gases lighter than air. You should experiment with other gases inside balloons.Less dense, or 'lighter than Air'.A one liter balloon filled with Helium and placed on a weigh scale will weigh less than the same balloon filled with air.Less *apex
The term you are referring to is called buoyancy. If the mass or density of a vapor or gas is less than that of dry air, it will be more buoyant and tend to rise in the atmosphere. Conversely, if the mass or density is greater than that of dry air, the vapor or gas will be less buoyant and tend to sink.
Air is another name for Oxygen, the gas we need to breathe in order to survive. Oxygen is an element on the periodic table of elements. Helium is an unreactive element that is even lighter than normal air. It is used commanly in party balloons, inflating huge objects, etc. But the masses are way different. All you need to know that helium is lighter than the air around us.
Yes, air pollution can and gas from cars
Gas. The Earth's atmosphere is composed of gases that make up the air we breathe.
The air around us help us to breath it carries to the gas that we need but it can also carry bad gases but that is unlikely. the gas we need are oxygen,nitrogen and carbon dioxide.
Oxygen gas makes up just over 20% of the air around us.

to keep us alive
If you mean 'floats', they were first used by Glenn Curtiss on many of the aircraft he built for the US Navy. Latwer floats became almost commonplace on many 'bush planes' in Canada and in the 1920's almost half of the Canadian Air Force aircraft were on floats.
80 %
There are many reasons why gases are important to us. For example, the air that we breathe is a gas.
i think maybe carbon dioxide
Yes, nitrogen is the main (80%) constituent of the air gas mixture, but oxygen (19%) is far more important to us!
No, it actually makes up around 80% of the air around us.
