How Does Location Affect the Number of Particles in the Air 

The following sample essay on “How Does Location Affect the Number of Particles in the Air “: what is air, what is wind, and other facts about the atmosphere.

Air is a very important thing on earth. Air density is 8 pounds per cubic foot or 1.3 kilograms per meter; air pressure is 14.7 pounds per square inch at sea level. At an altitude of 20,000 feet, the air pressure is 6.8 pounds per square inch. A person breathes about 35.274 pounds of air a day. This shows how important it is to humans’ everyday life.

But for some people particles in the air can cause asthma attacks. During an asthma attack “Your airways become swollen and inflamed. The muscles around the airways contract and the airways also produce extra mucus, causing your breathing (bronchial) tubes to narrow.” (mayoclinic.org) The point of this experiment is to see which location has the most air particles.

There are many things to question about the air like what it is made of.

The definition of air is “The gases that are throughout the earth and makes the earth’s atmosphere. Air is invisible and tasteless and usually doesn’t have an odor.” (New Standard Encyclopedia A-AND pg.168) Air has mostly nitrogen, oxygen, argon, carbon dioxide, water vapor, neon, helium, methane, krypton, and ozone. It’s composed mostly of nitrogen at 78% of the atmosphere and second-most of oxygen at 21%; the rest of the atmosphere is made of the other elements. The definition of oxygen is “a colorless, odorless reactive has the atomic number of 8 and the life-supporting component of the air.

Many creatures on earth can’t survive without it.” (Google Dictionary) The definition of nitrogen is “a colorless, odorless unreactive gas that is about 78 percent of the earth’s atmosphere.” (Google Dictionary)

Another thing related to air is the wind. The wind is caused by changes in atmospheric pressure which is created by uneven heating of the earth’s surface by the sun. Wind direction can be affected by the earth’s rotation. On earth that doesn’t rotate wind would move in a straight path from high to low-pressure areas. It is moved from this path to the northern and Southern Hemispheres by the turning of the earth. The wind can move particles in the air from location to location. Some particles that can be in the air are volcanic dust, pollen, spores of molds and algae, bacteria, soot, and pulverized earth. The Scatter of dust and other particles causes the sky at sunrise and sunset.

There can be special forms of air that are made by humans. There is compressed air, which forms when air is put in a smaller space than it naturally stays in and it has extreme pressure. There is liquid air, which is a very cold, pale-blue, substance. To liquify air it first has to be compressed which will raise its temperature next you have to cool the air; then it is allowed to expand, while it’s expanding its temperature drops letting some of the air liquify. There has been another person to do the science experiment to see what area has the most air particles. Their results showed the rural areas had the most air particles when compared to the urban sites. The data also showed that in the rural areas, the forest had the most air particles, the field the second most amount, and the road had the least. The road had the most air particles, but the forest had the second most, and the field the least.

This experiment tests the question “Which location has the most air particles?”. It is hypothesized that if vaseline-covered tabs are placed in the computer lab, in the gym, in my basement, and in the school storage room then the school storage room will have the most air particles trapped on the tab. This experiment could be helpful for people with asthma especially if more rooms are checked. Or it could be helpful to see what rooms need cleaning most often. In conclusion, this experiment can be useful for multiple reasons and helpful for tasks.
