Answer
They use jet fuel which creates carbon dioxide and other pollutants.
Man produces between 3 and 6% of all CO2 produced. Planes make up a very very small portion of the total CO2 we produce.
Air travel is a very energy-intensive activity. On average it generates about 200 grams of carbon dioxide (CO2) (7 ounces)per person, per air kilometre travelled.
So a 3000 km trip will emit 600 kg (0.6 tonnes) of CO2 for each person. A 747 Jumbo can hold between 400 and 600 people, so a plane carrying 500 people will generate 300 tonnes of carbon dioxide.
Planes don't use carbon dioxide, they create it by burning fuel in the engines.
Approximately 3 % of our carbon dioxide is formed by aircraft. See appended link for per plane calculation.
The appended link will allow calculation of CO2 emissions for wide range of commercial aircraft.
Photosynthesis is responsible for lowering the levels of atmospheric CO2 since it is a requirement to make glucose. Cellular respiration produces CO2 as a by-product, so it is responsible for some atmospheric CO2.
You will need to use a carbon scrubber device to capture co2 under atmospheric pressure.
Humans burning coal, oil and natural gas increases atmospheric CO2.Deforestation, cutting down trees, means that less carbon dioxide is removed from the atmosphere.Volcanic eruptions can put carbon dioxide into the atmosphere, but not nearly as much as fossil fuels.
Assuming ideal gas behaviour for CO2 and air, the mole fraction of CO2 in air wouldbe 0.000385 since the data of 385 ppm are given by volume.Then the partial pressure of CO2 in the atmospheric air is given by the product ofCO2 mole fraction and the atmosphere's total pressure.So, p.p.CO2 = 0.000385 x 14 psi = 0.00539 psi.Relation of psi to bar, 14.696 psi = 1.01325 bar.Finally, p.p.CO2 = 0.00539 psi x [1.01325 bar/14.696 bar] = 3.72 x 10-4 bar
This is so because CO2 is a green house gas which does not allow the harmful UV rays of the sun trapped by the Earth to go back , which increases the temperature of the Earth. So if carbon dioxide will increase , surely the temperature would also increase.
CO2 is in the air and as the air moves so does the CO2 in it.
Photosynthesis is responsible for lowering the levels of atmospheric CO2 since it is a requirement to make glucose. Cellular respiration produces CO2 as a by-product, so it is responsible for some atmospheric CO2.
yes, when it is released in large amounts than the normal natural percentage in air
The air bubbles lower the density of the solution
CO2 is rising rapidly. It is at least 25 percent higher than it was 400,000 years ago. CO2 increases slightly in the spring and summer and decreases during the fall and winter months.
Volcanism -- volcanoes -- are the greatest source of atmospheric CO2. After this, in varying degrees, are animal respiration, human energy generation, and transportation.
You will need to use a carbon scrubber device to capture co2 under atmospheric pressure.

CO2?
The percentage of expired air is around 74-80% Nitrogen. Because of gas exchange in the lung, expired air is also rich in CO2 and lower in O2 than atmospheric air (which has a 21.8% O2 comp and a .03 - .04% CO2 comp). Thus, the O2 and CO2 values narrow in difference to 14.5-16% and 4-5.5%, respectively.
Because the atmospheric CO2 concentration is part of the "Carbon Cycle" and biological and geological processes therefore affect it.
Atmospheric carbon dioxide (CO2).
