when you go diving, you take a pressurized tank of air, air consists of about 79% Nitrogen and 21% Oxygen, at normal pressure (atmospheric pressuer) the partial pressure of Nitrogen is 0.79 Bar and Oxygen 0.21 Bar which is safe.
Under high pressures (say 5 Bar which is at a depth of about 40 metres) the partial pressure of each gas increases Nitrogen (0.79x5=3.95Bar) which causes the lungs to absorb the nitrogen at a higher rate which influences the nervous system causing Narcosis (As if you're Drunk)
The reason why you can't take a tank of oxygen instead of air is that oxygen becomes toxic at higher partial pressures

What is the percentage of oxygen and helium in diving?
A mixture of helium and oxygen is commercially known as heliox and generally refers to a mixture of 21% O2 (the same as air) and 79% He, although other combinations are available.
Which gas law best explains diving medical problems?
Henry's law is the gas law that best explains diving medical problems. It describes how gases dissolve in liquids, such as nitrogen dissolving in blood and tissues during scuba diving. This can lead to decompression sickness if the nitrogen is not properly eliminated from the body.
How does nitrogen dilutes the action of oxygen?
Nitrogen dilutes the action of oxygen in breathing air by reducing the concentration of oxygen available for cellular respiration. This can lead to hypoxia, a condition where there is a lack of oxygen in the body tissues. This is a concern in environments with high nitrogen content, such as scuba diving, where nitrogen narcosis can occur due to the effects of increased nitrogen pressure.
What is the chemistry behind scuba diving at 3pmand flying on an airplane at 7pm the same day?
It is not chemistry, but more physics. Many think it is a simple formula and your questions should be able to be answered, but the body does not respond the way forumlas calculate. The current flying after diving recommendations are to wait 12 hours to fly if a single dive was made, and if multiple dives were made then wait 18 hours.
Can a human being dive to 400 feet with oxygen tanks?
no. oxygen and pressure is a lethal combination... 400ft has just to much pressure..you will need nitrous to dive that deep... which is very dangerous.AdditionYes, technical divers can dive to 400 feet. But they do not breathe pure oxygen (or nitrous on the bottom). They breath a combination of helium, oxygen and nitrogen known as trimix.
Is nitrogen in a diving tank a solid liquid gas or plasma?
Nitrogen in a diving tank is in a gas state. When compressed into the tank, it remains in a gaseous form until it is released and breathed in by a diver.
Which alteration of consciousness during deep sea diving is knows as?
Nitrogen Narcosis (martini Effect) also known as ruptures in deep sea diving.
What are the properties of fluids that can make scuba diving dangerous?
The propertie that make the fluids dangerous is nitrogen.
Which gases go into diving cylinders?
There are various mixes of gases which can be used in diving tanks. The most commonly used one for recreational diving is normal air which consists of 80% nitrogen and 20% oxygen (and a small amount of carbon dioxide, argon and other gases) Sometimes the proportion of nitrogen - oxygen is change as follows: Air (80% nitrogen and 20% oxygen) Nitrox-28 (72% nitrogen and 28% oxygen) Nitrox-30 (70% nitrogen and 30% oxygen) Nitrox-32 (68% nitrogen and 32% oxygen) Nitrox-34 (66% nitrogen and 34% oxygen) These are just examples but different mixes can be made You can also use mixes of nitrogen, oxygen and helium. this mix is called trimix. Hope that helps
Why may going to altitude after diving be a problem?
Going to altitude after diving can be a problem because the change in pressure can cause the nitrogen in the body to expand, leading to decompression sickness or "the bends." This can result in serious health issues such as joint pain, dizziness, and even paralysis. It is important to wait a certain amount of time before going to high altitudes after diving to allow the body to safely release the nitrogen.
What is the percentage of oxygen and helium in diving?
A mixture of helium and oxygen is commercially known as heliox and generally refers to a mixture of 21% O2 (the same as air) and 79% He, although other combinations are available.
Why are diving accident victims placed in a hyperbaric chamber?
Diving accident victims are placed in a hyperbaric chamber primarily to treat decompression sickness, also known as "the bends." This condition occurs when nitrogen bubbles form in the body due to rapid ascent after deep diving. The hyperbaric chamber increases atmospheric pressure, allowing the nitrogen bubbles to dissolve back into the bloodstream and reducing the risk of tissue damage. Additionally, the chamber can enhance oxygen delivery to tissues, aiding in recovery from injuries related to diving.
What is consciousness during deep sea diving called?
i- Raptures of the deep, ii- Martini Effect, iii- Nitrogen Narcosis both.
How could nitrogen be used as a explosive?
Nitrogen by itself does not support combustion. But if pressuring a vessel with nitrogen and allowing it to overpressure (beyond vessel limits) a vessel can explode by fatigue. Under pressure, for example when scuba diving, yes, but otherwise, I don't think so.
What is the symbol for nitrox?
The symbol for nitrox, which is a mixture of nitrogen and oxygen used in diving, is typically represented as "EANx" where "x" denotes the percentage of oxygen in the mixture. For example, EAN32 refers to a nitrox blend containing 32% oxygen and 68% nitrogen. In diving contexts, it's important to specify the oxygen percentage for safety and planning purposes.
The gas element used in deep-sea diving?
Deep-sea diving act of descending into deep water, with some breathing apparatus, help them to remain there for an extended period. There can be multiple gases used depending on desired depth and length of dive the common is a tri-mixed gas of Nitrogen, Oxygen, and Helium.
What water sport is the most dangerous Out of swimming water skiing surfing scuba diving snorkeling kayaking or canoeing?
I would say scuba diving. You can get the bends, or nitrogen narcosis. There is also the factor of running out oxygen during a dive.
