It is exactly like coke...
When the bottle is closed there are no bubbles because the pressure in the bottle is higher than the pressure outside the bottle. When you open the bottle you let the pressure out and now the coke is at the same pressure as the air around you. As a result the CO2 escapes the coke and you see bubbles.
Air is only a small part Oxygen. Air is mostly Nitrogen. When a diver goes underwater the nitrogen is pushed into his blood like the coke in the example. If he comes up too quickly then his blood acts like the coke in a freshly opened bottle and the nitrogen bubbles out.

∙ 14y agoThey can die because of the Bends, nitrogen narcosis, and the other risks of Scuba diving. I'm not fully sure, because I am only basically certified and not nitrox certified.
Nitrogen is actually not "used" in scuba diving, it is a natural element of air. The problem with nitrogen is it dissolves into tissues at depths which can cause the problems which can lead to the death of a diver. Excessive nitrogen dissolved into the divers tissues at depth can cause Nitrogen Narcosis which is kind of like a drunken state for the diver. The diver can experience paranoia, overconfidence, disorientation, etc.
As the diver surfaces from depth, the nitrogen that was dissolved into the body is released. This nitrogen is managed by controlling the ascent of the diver and allowing it to work it's way slowly out of the divers system and expelled with exhalation. If a diver surfaces too fast he is unable to expel the gas slowly and it forms bubbles in his blood stream, a problem commonly known as the Bends or DCS (Decompression sickness).
In order to help avoid these problems, deep divers use something called mixed gasses, most commonly Trimix (Oxygen, Nitrogen, and Helium) or Heliox (helium and oxygen) to lower the amount of nitrogen absorbed into the body and reducing the risk of nitrogen based problems.

Why are astronauts are trained in scuba diving?
It simulates weightlesness and using tools in a confined environment. Good training for Nauts.
What exactly is scuba diving?
Literally, scuba diving means using diving underwater using Self Contained Underwater Breathing Apparatus.Conventional scuba equipment usually consists of a cylinder of compressed air (worn on the diver's back), and a "regulator" which converts the air from being highly compressed and delivers it to the diver at a breathable pressure.Scuba equipement also technically include rebreathers, which are a much more sophisticated form of diving equipment, whereby the air which the diver breathes is constantly recycled through a carbon dioxide scrubbing system.Scuba diving is now a popular recreational holiday activity, with over 10 million certified scuba divers worldwide.
What do you set to catch lobsters?
Most people catch lobsters by using lobster traps or pots. Some people are free diving scuba divers who swim in the water and catch the lobsters that way.
Is oceanography mainly scuba-diving?
Oceanography is like geography in the sea. You study the geography of the seabed and the nature of the water, such as salinity, turbidity currents etc. Although oceanographers may like scuba diving it is unlikely that is will be part of their job because using SCUBA you can only visit a tiny amount of the oceans. Lots of oceanographers are involved in oil exploration for example where the water would be far to deep to reach with scuba.
How do you dive?
When your pokemon uses surf and you see a dark patch of water move on top of it and click the A button and you dive into a old ruin.
Which is the most reliable brand of marine electronics for filming a scuba diving expedition?
When shooting film underwater, such as in a scuba diving expedition, the brand of electronics or type of camcorder you are using that is the most important piece of equipment. The camcorder housing, which prevents the camcorder from getting wet, is essential. Housings are available from Gates Underwater Products or Amphibico.
What is skin diving?
Skin diving is any underwater activity done without the use of SCUBA gear, using a mask and flippers, and possibly a snorkel.It includes swimming, spear fishing, free dive photography, competitive breath-hold free diving and other apnea competitions.
You want to convert a SCUBA tank for use as CNG tank?
the silly answer is you can store anything in a scuba tank that you can get in it!!. BUTthe serious answer is scuba tank were designed for compressed air and nothing else... using a scuba tank for natural gas is like driving around with a bomb in your car!!, the valves and collars of the bottles are not strong enough if there was a crash
What is scooter scuba diving?
"Scuba scooter" is usually just slang for a diver propulsion vehicle (or DPV). It is basically like a torpedo with handles that a diver can ride. It enable the diver to go further, faster and using less air (because she gets less tired from swimming).
