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.
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.
When liquid CO2 is exposed to air, it quickly evaporates and turns into gaseous CO2. This process is known as sublimation. The gaseous CO2 will mix with the air in its surroundings.
Carbon dioxide (CO2) is the atmospheric gas that enables green plants to carry on the process of photosynthesis. Plants absorb carbon dioxide from the air and convert it into sugars and oxygen through the process of photosynthesis.
No, it is higher or the CO2 would not move out of the lungs.
CO2 is in the air and as the air moves so does the CO2 in it.

yes, when it is released in large amounts than the normal natural percentage in air
Volcanism -- volcanoes -- are the greatest source of atmospheric CO2. After this, in varying degrees, are animal respiration, human energy generation, and transportation.

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.
Atmospheric CO2 levels have been rising steadily over the past 50 years due to human activities such as burning fossil fuels and deforestation. Seasonal fluctuations occur due to natural processes like plant growth absorbing CO2 in the spring and summer, and releasing it back in the fall and winter. However, the overall trend shows a significant increase in atmospheric CO2 concentration.
Atmospheric carbon dioxide (CO2).
yes but only the ambient CO2 it is a NITROX mask for elevated O2 between 40 and 60 % the rest is AIR which contains Co2 at atmospheric pressure.. 1 BARAdditionAssuming you are talking about some kind of full face diving mask with a regulator attached, you will be rebreathing some gas you have exhaled. So yes, you will be rebreathing CO2 - which will be at a greater concentration as well as a greater partial pressure than the CO2 at atmospheric pressure. But it will be minor amounts. However if you are talking about a hospital type of application then it is a different answer.
CO2 is produced from the poisonous smoke from cars, factories etc. Natural sources of atmospheric carbon dioxide include from volcanic outgassing, the combustion of organic matter, while aerobic respiration, burning of fossil fuels etc.
