Because they have a air tank to help them breath.
What else can I help you with?
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.
Why are deep sea divers not supplied with ordinary air?
because under the sea atmospheric pressure is high
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 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.
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.
How long would a air tank last on the moon?
Can not answer this question. Need to know:Size of air tankWho or what we are supplying the air too.Finally are we reusing the air as much as possible or using a total loss system like scuba divers use.
How do divers get their air?
Divers typically get their air from a tank filled with compressed air, which they carry on their backs. This tank is connected to a regulator that controls the flow of air, allowing divers to breathe comfortably underwater. In some cases, divers may use alternative gas mixtures, such as nitrox or trimix, to extend their dive time or enhance safety. Surface-supplied diving systems are another option, providing air through a hose from a support vessel.
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.
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).
Why did Jacques cousteau invent the aqualung?
Jacques Cousteau invented the Aqua-Lung to allow divers to explore underwater for longer periods without needing to surface frequently for air. This invention revolutionized underwater exploration by providing divers with the ability to breathe underwater using compressed air tanks.
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 is the main disadvantage of using an ordinary bicycle tire?
Well, they're air-filled and under pressure, and as such prone to leaks and punctures.
