What helps breathe under water?
Divers carry with them tanks containing air in them. The air present in these tanks has different composition from the normal air. It has 32% oxygen, 56% Nitrogen and 12% Helium. It is done so as to avoid creation of bends inside the body of divers when they come out of water.

Would a scuba divers tank filled with compressed air last longer than normal pressure air?
It definitely would. Also, a tank filled with non-compressed air would be nearly impossible to use because air wouldn't flow out of it without an enormous amount of effort. For these reasons, all tanks used by divers are filled with compressed air.
Mixture of gases for scuba diving tanks compared to normal atmospheric air?
Most SCUBA divers dive with compressed air, which is normal atmospheric air compressed into a scuba tank.
Why does a scuba diver need increased gas in the air tank?
Scuba divers require increased air pressures in their air tanks while diving because the pressure on their bodies increases.
What helps a diver breath?
Divers wear tanks full of oxygen to help them breathe while they are under water. When the tanks start to get empty, they resurface.
Where you can find helium from your surrounding?
Air is a mixture of gases in which helium is present in atmosphere.It is mostly present in oxygen tanks used by sea divers and in balloons.
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.
How do scuba divers refill their air tanks?
They either go to a dive shop or have their own compressors. An average 80 ci tank costs roughly $5usd to fill
How do scuba divers sink if they have tanks of compressed air on their backs?
The average aluminum SCUBA cylinder holds 80 cubic feet of air at pressure. That means you are taking the equivalent of a closet's worth of air and smashing it into a cylinder much smaller than that. When full, the cylinder is at 3,000 pounds per square inch of pressure.When the valve is opened, it sends air into the (assumed) first stage regulator which is connected by hoses to gear such as two second stage regulators, instruments and your vest.So the SCUBA tanks don't so much USE the air so much as STORE the air at high pressures.
If there is no oxygen on the moon then how does the man in the moon breathe?
By oxygen tanks - similar to SCUBA divers.
How do scuba divers alter their average density to float?
Divers usually increase their density by wearing a weight belt (which contains lead weights). Some divers also rely, to a lesser degree, on using steel tanks, which are more dense than aluminum tanks. To decrease their density, divers put air into a Bouyancy Control Device (BCD). Some divers may also control bouyancy by putting air into a drysuit if they wear one. Whereas the increase in density created by the weightbelt is normally fixed, the positive bouyancy provided by the BCD can be varied throughout the dive. Usually a divers net density will decrease over the dive - a diver with a full scuba tank has about 4.5 lbs of extra weight (the weight of the gas) over a diver with an empty scuba tank.
