By mole fraction(i.e., by quantity of molecules), dry air contains 78.08% nitrogen, 20.95% oxygen, 0.93% argon, 0.04% carbon dioxide, and small amounts of other trace gases. Air also contains a variable amount of water vapor, on average around 1% at sea level, and 0.4% over the entire atmosphere.
29 lip 2024 · Learn about the main components of Earth's atmosphere, including nitrogen, oxygen, water vapor, and carbon dioxide. Find out how air composition varies by region, time, and altitude.
Air, mixture of gases comprising the Earth’s atmosphere. The mixture contains a group of gases of nearly constant concentrations and a group with concentrations that are variable in both space and time. The atmospheric gases of steady concentration (and their proportions in percentage by volume)
1 lut 2021 · About 99% of the composition of air consists of nitrogen, oxygen, and argon. Water vapor (variable) and carbon dioxide are the main trace gases. There is no chemical formula for air because the Earth’s atmosphere consists of a mixture of gases.
Learn about oxygen, a chemical element that forms a colorless gas and is essential for life on Earth. Find out how oxygen is produced, used, and affected by photosynthesis, respiration, and pollution.
11 sie 2020 · When we take up air in our lungs, oxygen travels to all cells in the body and reacts with nutrients in our food such as fats and carbohydrates, providing the energy that keeps us alive. In the air we breathe out, part of the oxygen is replaced by carbon dioxide and water, two of the products of oxidizing nutrients.
