Do scuba divers breath pure oxygen?

Believe it or not, we can die from too little oxygen AND too much oxygen. This concept involves partial pressures. If we first consider using standard air (i.e. 20% Oxygen and 80% Nitrogen): (1 bar = 1 kilogram of pressure per square centimetre) At the surface - Total Pressure of air = 1 bar - Pressure of Oxygen = 0.2 bar - Pressure of Nitrogen = 0.8 bar At 10m - Total Pressure of air = 2 bar - Pressure of Oxygen = 0.4 bar - Pressure of Nitrogen = 1.6 bar At 20m - Total Pressure of air = 3 bar - Pressure of Oxygen = 0.6 bar - Pressure of Nitrogen = 2.4 bar At 30m - Total Pressure of air = 4 bar - Pressure of Oxygen = 0.8 bar - Pressure of Nitrogen = 3.2 bar At 40m - Total Pressure of air = 5 bar - Pressure of Oxygen = 1.0 bar - Pressure of Nitrogen = 4.0 bar At 50m - Total Pressure of air = 6 bar - Pressure of Oxygen = 1.2 bar - Pressure of Nitrogen = 4.8 bar At 60m - Total Pressure of air = 7 bar - Pressure of Oxygen = 1.4 bar - Pressure of Nitrogen = 5.6 bar At 70m - Total Pressure of air = 8 bar - Pressure of Oxygen = 1.6 bar - Pressure of Nitrogen = 6.4 bar It is at the partial pressure of 1.6 bar (which occurs at 70m where oxygen becomes toxic. That is why most dive organisations recommend 50m as a maximum for recreational diving. However, if pure oxygen is used: At surface - Pressure of Oxygen = 1 bar At 10m - Pressure of oxygen = 2 bar The oxygen has already become toxic! Hope that answers your question. The concept is called "partial pressures" and "oxygen toxicity" if you want to research more on a search engine.


How deep can a scuba diver go on compressed air?

If the gas is normal air (~20-22% oxygen), the maximum recommended depth of most dive organisations is in the region of 50-60m. The reason for this is that the deeper you go, the higher the pressure of the water. For example, on the surface, the pressure is 1 bar, 10m is 2 bar, 20m is 3 bar 30m is 4 bar etc. Oxygen becomes toxic to the human body at about 1.6 bar so if you are at 70m, with a mix of 20% oxygen, you are at 8 bar of pressure. At 8 bar, the parital pressure of oxygen is 1.6 bar, enough to become toxic. So compressed air becomes dangerous at 70m so most organisations advise to go no deeper than 50-60m. If you use a different gas blend, such as Nitrox ar Trimix, the amount of oxygen is different so the depths are different too. In summary, on compressed air, the maximum is about 70m, recommended 50-60m max.


What does nitrogen have to do with diving?

Nitrogen is a component of air that is breathed during diving. Due to the increased pressure underwater, nitrogen can dissolve into body tissues, leading to a condition called nitrogen narcosis or "rapture of the deep," which can impair judgment and coordination at certain depths. Rapid ascent from a dive without proper decompression can also lead to nitrogen bubbles forming in the blood, causing decompression sickness or "the bends."

How do you make nitrogen?

Nitrogen is typically obtained by fractional distillation of liquid air, which separates nitrogen from oxygen, argon, and other gases. Alternatively, nitrogen can also be produced by the process of pressure swing adsorption, which involves selectively adsorbing nitrogen gas molecules. Additionally, certain industrial processes such as the Haber-Bosch process can be used to convert atmospheric nitrogen into ammonia, which can then be further processed to obtain pure nitrogen gas.


What is the squiggle line called on the y axis of a graph?

When you are changing a scale on a graphic, you warn the viewer by using a squiggle line on the changed axis. If the bar is unusually long, the bar length is compressed with a squiggle in the bar itself.


How many cubic meters of gas at 200 bar in one liter?

One liter of gas at 200 bar would expand to approximately 0.2 cubic meters (200 liters) if the pressure is reduced to atmospheric pressure (1 bar).
