There are a numerous ways through which oxygen can be separated from air. One way is through the usage of fractional distillation of air. This is done by lowering the temperature of air while increasing the pressure. When water vapour and liquid air have cooled off, they are extracted as liquids and then the remaining air is cooled further until a temperature of 90K where the liquid oxygen coos off and is collected and stored in an insulated container.
Yes, you could consider air a gas, but air on earth is more commonly thought of as a collection of gases: oxygen, nitrogen, etc.But on the other side, "gas is air" is not correct. When we talk about "air", we talk about the specific combination of gases that we breathe.In other words, you would not say that a jar full of methane is air, but you could say that a jar full of air is a gas.
yes because the air is more dense at lower altitudes
The Earth's atmosphere is composed of roughly 21% oxygen. This level of oxygen in the air is ideal for human respiratory needs.
Around 16% of the air you breathe out is oxygen. This percentage decreases from the 21% of oxygen in the air you inhale due to the exchange of gases that occurs during respiration.
Oxygen is approximately 21% of the air we breathe.
Whales store air In their lungs and oxygen in their blood. Humans do the same thing, but we're not as good at as whales.
Carbon and Oxygen are different elements.
No, humid air does not have less oxygen compared to dry air. The amount of oxygen in the air remains the same regardless of humidity levels.
Yes, Air is a mixture of oxygen, nitrogen, carbon dioxide, water vapor, and pollutants.
No, oxygen is a chemical element, while oxidation is a chemical reaction that involves the loss of electrons by a substance. Oxygen is often involved in oxidation reactions, but they are not the same thing.
It has the same density as air.
Air is mainly a mix of oxygen and nitrogen. Oxygen is the part your body uses- the good stuff.
Ozone can be made in air, or in varying concentrations of oxygen and air. Some salesmen think "new" names are helpful, so this is probably "oxone" = "ozone made in oxygen for a parent gas". When it gives you a headache, it will smell sweeter when doing it.
same thing
...From the air. They're mammals, they get their oxygen the same way as all other mammals.
It has the same density as air.
Actually, it is about the same thing, lack of oxygen.
