Volcanism -- volcanoes -- are the greatest source of atmospheric CO2. After this, in varying degrees, are animal respiration, human energy generation, and transportation.

Why CO2 is more in alveolar air than expired air?

Alveolar air mixes with air in the anatomic dead space on its way, which is rich in oxygen. hence % of oxygen is more in expired air. Thus though amount of CO2 does not decrease, percentage decreases as inspired air contains very less amount of CO2 (0.03%).


What is the density of co2 gas compared to the air in the room?

CO2 gas is more dense than the mixture of air we breathe. You can see this when dry ice sublimates.


What is in the air water or land that can be harmful to non living and living things?

In the air, there are many gases that are harmful. Like Co2 (Carbon Dioxide). But there is so little amounts of Co2 in the air that it doesn't effect us, but the more we pollute and burn fuels the more Co2 there will be in the air. And the non-living side, there is no harmful thing to a abiotic (non-living). you can smash a rock on the floor and nothing will happen to you to cause pain. Unless you're in love with the rock :D Hope this helped.


Which gas is more plus abundant in exhaled air than inhaled air?

Carbon dioxide (CO2).


What kinds of things do dolphins do?

Dolphins sometimes blow air bubbles when they are bored.


What gas is more abundant inhaled air than exhaled air?

CO2. Oxygen decreases after diffusion into the blood and CO2 being released in respiration is expired in greater concentrations.


Would co2 push something faster than air?

Yes, Co2 packs more of a punch than compressed air. They use Co2 for paint ball guns, and regular paint guns. It is also used for some BB or Air Soft guns.


What gas is released by living things into the air is utilized by plants?

Carbon Dioxide, or commonly known as CO2


what is Lili?

A Peace Lily is a type of flower that can clean the air from dust mites and other things such as CO2.


Will Carbon Dioxide Fall from Warm Air?

No. If anything, the warmer the air, the more turbulent it is, more thoroughly mixing CO2. Sometimes in caves and mine shafts, where the air is very still, CO2 settles out into fairly high concentrations. Bats can survive CO2 levels more than a hundred times higher than what is lethal to people. But in general, once CO2 gets into the air the only thing that pulls it back out is the sequestration activity of photosynthetic organisms. Cf. Azolla Event.


What happens when liquid co2 is exposed to air?

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.


What compound in air contains carbon?

Carbon is in most of the chemicals in living things and is in the air in carbon dioxide gas.
