Air is 21% oxygen so 21% of 200 is 42 oxygen molecules.
Oxygen gas diffuses faster than air because oxygen molecules are smaller and lighter than the molecules of air, which is mostly composed of nitrogen and oxygen. This allows oxygen molecules to move more quickly through a medium, such as air or other gases.
air molecules are , nitrogen , oxygen, and carbon dioxide mosly nitrogen (75%)
Yes, cold air typically has more oxygen compared to warm air because cold air is denser and can hold more oxygen molecules.
Yes, air molecules do have mass. Air is made up of various gases such as nitrogen, oxygen, and carbon dioxide, and each of these gas molecules contributes to the overall mass of the air.
Air: 78% nitrogen, 21% oxygen, 1% other. We breathe oxygen and other molecules.
At higher altitudes, the air pressure decreases because the air molecules are more spread out. This reduction in pressure means there are fewer oxygen molecules available in the air to be breathed in, leading to lower oxygen levels at high altitudes.
They get air from a generator that splits water molecules into hydrogen and oxygen!! :) Hope it helped!!
Plant use carbon-dioxide for respiration. They absorb the carbon molecules and release the oxygen molecules into the air.
Yes, cold air typically contains more oxygen than warm air. This is because cold air is denser and can hold more molecules, including oxygen.
Conc'n of O2 is 20 % For nirogen it is 79% Other gases us 1% , this included water vapour, carbon dioxide, the noble(inert) gases. The partial pressure of oxygen p(O2) = 20/100 = 1/5 = 0.2
Nitrogen, oxygen (including ozone), carbon dioxide
