CARBON DIOXIDE: Carbon dioxide only makes 3 out of 10,000 atoms/molecules of air; however, it supplies the carbon that plants use to make leaves, trunks, roots, etc. It's hard to believe that the weight of giant redwood trees came from the small amount of carbon dioxide gas in the air.

Gas mixtures are any combination of two or more components. Air Products has a wealth of experience in the production and supply of gas mixtures, whether they're simple two component or highly complicated with 50 components or more.

As a gas it makes up 20% of the air. Some oxygen gas is dissolved in water, and some oxygen gas is in the pores in the ground. However, there's a lot more oxygen in this picture that we don't normally consider. 90% of the weight of the water in the river is oxygen atoms.

8 out of 10 atoms (or molecules) of air are made of nitrogen. Nitrogen gas can't be seen but when it is cooled to -320 °F (-195°C) it turns to a liquid, which you can see. Being this cold makes it handy for many things.

The same would be true of particles and other pollutants in the air. TO THE EDGE OF SPACE. All of those gases and particles are not evenly distributed in the atmosphere, And the atmosphere is not evenly distributed by mass or weight. The densest and heaviest part of the atmosphere is near the Earth. The atmosphere becomes thinner as you go higher above the Earth's surface.

There are many things in the atmosphere, but basically it is made up of two different elements which are gases. Measured by volume (not weight) completely dry air contains approximately 78% nitrogen and 21% oxygen with about 1% of everything else.

About 50% of the mass of the atmosphere is located below an altitude of about 18,000 feet (5.6 km). About 90% of the atmosphere's mass is below an altitude of 52,000 feet (16 km). Almost all of the atmosphere's mass (99.99997%) is located below 330,000 feet or 62 miles (100 km). That altitude of 100 km is considered by many people to be the edge of space-the boundary between the Earth's atmosphere and outer space.

Here are 10 gases that make up clean air: In order of highest to lowest concentration they are Nitrogen, Oxygen, Argon, Carbon dioxide, Neon, Helium, Methane (CH4), Krypton, Hydrogen, and Xenon. Five of them travel alone, so we call them atoms.

The volume of the balloon in the video shrinks when the trapped gas particles slow down with the addition of extremely cold nitrogen. The temperature of any physical system is related to the motions of the particles (molecules and atoms) which make up the [gas] system.

Gas is one of the four fundamental states of matter (the others being solid, liquid, and plasma). A pure gas may be made up of individual atoms (e.g. a noble gas like neon), elemental molecules made from one type of atom (e.g. oxygen), or compound molecules made from a variety of atoms (e.g. carbon dioxide). A gas mixture would contain a variety of pure gases much like the air. What distinguishes a gas from liquids and solids is the vast separation of the individual gas particles.

air is made up of what gases
Air is made up of Nitrogen, Oxygen, Argon, Carbon dioxide, Neon, Helium, Methane, Krypton, Hydrogen, and Xenon. Air is made up of Nitrogen, Oxygen, Argon, Carbon dioxide, Neon, Helium, Methane or CH4, Krypton, Hydrogen, and Xenon.
