∙ 13y agoThe level of gasses maintains an equilibrium within a solution and outside pressure. This is why soda pop fizzes when you remove the cap. When a diver descends, he/she breathes in air at increasingly denser pressures, more gasses can be stored with in the blood. As you rise, the pressure becomes less and so the gases come out solution of the blood. If you do not gradually rise into decreasing pressure, and breath out those gasses gradually as you rise, then they can form an embolism. Which can be very painful. For this reason schedules of how divers should ascend to the surface have been compiled. Deep Sea Divers sometimes do what is called "saturation diving" where they live in a pressure chamber which is set at the depth that they are diviing to. This way they can go directly to and from the desired depth, living in the pressurized chamber on the surface, when they are not diviing. In this way the eqliubrium of that depth is maintained.

Why deep sea divers not using ordinary air?
Because they have a air tank to help them breath.
How does an air pocket underwater remain constant when divers expel air into it?
Air pocket formed is due pressure. Air made of mass and and if enclosed areas, water rush in and push air against wall. If not enclosed, air will reach top surface as air bubble.
Can you use helium in an air balloon not hot air just ordinary party balloons?
yes, but when using Helium you must have the balloon completely sealed and used a mylar material for the balloon as Helium 'leaks-out' of ordinary materials.
Can a diver go seven miles down to the bottom of the ocean?
they can go 1000 meters down !!! . but they have to have a tree near them Additional: There have been navy tests in cambers which divers have been under pressure to simulate dives to 2000 feet. Since most of the body in made up of uncompressable water in theory a diver could go to unlimited depth as long as the air he is breathing is reduce in oxygen and nitrogen to keep him from convulsing. And at a high enough pressure so his lungs would be equalized.. Question is how long would it take to come back up from deep deep "dive" with all the decompression needed. Tim
What are the things that move with the help of air?
every things in world move only because of the presence of air , any for this question yatches , planes etc will be the answers.
Why deep sea divers not using ordinary air?
Because they have a air tank to help them breath.
Before a diver dives will he will take a deep breath or hyperventilate?
Free divers do but scuba divers do not need to. Scuba divers take their air with them and would have no need to hyperventilate.
Why do scuba divers need math?
they need to know how long they can be underwater, and how deep they can go with the air in the tank.
What is the mixture of gases in a deep sea divers air tank?
95-98%helium 2-5% Oxygen
Why isn't it a good idea for divers travelling by air straight after a deep dive?
So they dont get the bends and the co2 levels in the body have time to equalize.
What is the name of a compressed air cylinder used in skin diving?
Divers (and others) call the compressed air cylinders used by divers tank(s) or SCUBA tank(s).
What has the author Peter B Bennett written?
Peter B. Bennett has written: 'The physiology and medicine of diving and compressed air work' -- subject(s): Deep diving, High pressure (Science), Physiological aspects, Physiological aspects of Deep diving, Physiological effect, Submarine medicine 'The Physiology and Medicine of Diving' 'To the very depths' -- subject(s): Anesthesiologists, Divers Alert Network, Divers, Biography
How can the increase in the level of nitrogen be avoided by deep sea divers?
By breathing nitrox (gases where the %O2 is higher as compared to air) or mixed gases (e.g. adding in helium) so that the partial pressure of nitrogen is reduced.
What kind of gas do divers use?
Divers use 21% Oxygen and 79% nitrogen while underwater. It results in the same exact air we breath on the surface.
Why cant ordinary air be used if a dive is very deep?
Oxygen is toxic above partial pressures of 1.6, which is a little less than 8 atmospheres, or 230 feet.
How do you do deep diving in the ocean?
Deep diving in the ocean is done very carefully in special suits and helmets. Pressure under the ocean is significant and can be immense by the time you are down a few hundred feet. Scuba diving is sometimes used commercially, but only to depths of about 120 feet. - Many large dockyards and navies employ 'clearance divers ' to repair items on the bottom of ships and work on the dockyard floor. These divers wear heavy canvas suits and large hard helmets, fed air by lines from the surface. They can work down to 300 feet deep or so. Research and oilfield divers can wear special hard suits that allow them to go down almost 1,000 ft. These divers often wear "Newt suits" made by the Canadian company Nuytco Research in Vancouver.
What type of invention did Edmond Halley invent?
The only invention i think he invented was the diving bell. It was a bell that allowed divers to stay at about 60 ft (18 m) for an hour and a half under water. The bell is made of a wooden shell with windows to let in light from the surface. Air was supplied to divers through leather tubes connected to air casks that could be lowered into the water when needed. These early inventions led to the development of more sophisticated diving bells that are used today.
