What else can I help you with?
What diffuses faster air or oxygen gas why?
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.
What air molecules?
air molecules are , nitrogen , oxygen, and carbon dioxide mosly nitrogen (75%)
Does cold air have less oxygen compared to warm air?
Yes, cold air typically has more oxygen compared to warm air because cold air is denser and can hold more oxygen molecules.
Do air molecules have mass?
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.
What do people breathe?
Air: 78% nitrogen, 21% oxygen, 1% other. We breathe oxygen and other molecules.
Why the pressure of oxygen becomes low at high altitudes?
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.
How does the iss get air?
They get air from a generator that splits water molecules into hydrogen and oxygen!! :) Hope it helped!!
How come plants produce oxygen even though they need oxygen for respiration?
Plant use carbon-dioxide for respiration. They absorb the carbon molecules and release the oxygen molecules into the air.
Does cold air contain more oxygen than warm 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.
What is concentration oxygen in air?
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
What are 3 gases in the air which are molecules?
Nitrogen, oxygen (including ozone), carbon dioxide
Oxygen the air comnbines with iron molecules on a frying pan to form?
Rust
