When we breathe in air, we take in oxygen to be used in cellular respiration. During this process, the body produces carbon dioxide as a waste product. When we breathe out, the exhaled air contains a higher concentration of carbon dioxide because it is being expelled from our body after the oxygen has been used up.
Yes. When you breath, you take in oxygen and breathe out CO2. According to Wiki Answers (see link), an exhaled breath is about 4% CO2. Atmospheric CO2 is between 300 and 400 ppm, or 0.03% to 0.04%.
No, carbon dioxide is heavier than helium. Carbon dioxide has a molecular weight of about 44 g/mol, while helium has a molecular weight of 4 g/mol. This means that helium is lighter than carbon dioxide and will rise above it in the presence of air.
Carbon Dioxide do exist in universe in places other than Earth.
Carbon dioxide diffuses faster than sulfur dioxide because carbon dioxide is lighter and has a lower molecular weight, allowing it to move more quickly through the air. Additionally, carbon dioxide molecules are smaller in size, which also contributes to their faster diffusion rate.
Carbon dioxide has a higher density than air. This is why it can accumulate in low-lying areas and pose a risk of asphyxiation if not properly ventilated.
As there is a low level of carbon dioxide in the air that animals (and people) breath, yes every breath taken in breaths in some carbon dioxide.But as carbon dioxide in the blood is transferred to the air in the lungs, increasing the level of carbon dioxide in that air, when they breath out both the carbon dioxide breathed in and the additional carbon dioxide from the blood are breathed out. Thus in balance more carbon dioxide is breathed out than is breathed in.
breathed out air turns lime water cloudy than breathed out air cuz the carbon dioxide content present in breathed out air(0.04% approximately) as compared to breathed out air(4% approximately)so as CO2 passes through lime water it turns lime water cloudy:)
Carbon dioxide Nitrogen Water vapor (and believe it or not you also breath out Oxygen - although less than you breathed in).
In the lungs, carbon dioxide is concentrated more in the blood. The alveoli keeps the carbon dioxide at a lower level than in the blood.
The air you breathe out has different amounts of oxygen, nitrogen, carbon dioxide and a few other substances in it than the air you breathed in. Your lungs absorb a lot of the oxygen, for example, which is then carried by red blood cells to your heart and muscles. Your body also produces carbon dioxide as a kind of waste product which is in the air you breathe out. So the air you breathe out has less oxygen but more carbon dioxide than the air you breathed in did. There are also other smaller changes that you could look up.
Carbon dioxide is more dense than air.
Trees act as carbon sinks by absorbing carbon dioxide from the atmosphere during photosynthesis and storing the carbon in their trunks, branches, leaves, and roots. This helps to reduce the amount of carbon dioxide in the atmosphere, which helps mitigate climate change by lowering greenhouse gas levels.

Humans breathe in whatever happens to be in the air when they breathe in. If there is carbon dioxide then they will breathe it in as well as nitrogen and oxygen. However they only use the oxygen for respiration so they breathe out everything else with extra carbon dioxide.
No, carbon dioxide is heavier than helium. Carbon dioxide has a molecular weight of about 44 g/mol, while helium has a molecular weight of 4 g/mol. This means that helium is lighter than carbon dioxide and will rise above it in the presence of air.
In an atmosphere of carbon dioxide, warm carbon dioxide would rise. Since carbon dioxide is better than twice as dense as air, it would need to be really hot before it would rise.
Carbon Dioxide is less denser than air.
