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.
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 deep sea divers not using ordinary air?
Because they have a air tank to help them breath.
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.
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.
Why do people use air?
We need air to breath. Otherwise we would suffocate and die. That is why scuba divers have special equipment to allow them to have air to breath underwater.
What risk were the divers exposed to?
1.Being Eaten By Sharks 2.Running Out Of Air 3.
Does a divers bouyancy change with depth?
Absolutely - air compresses at depth, and because wetsuits are made up of air cells, they compress and lose buoyancy along with the air in the BCD, so divers have to add air while descending. Also, as you breathe air, the tank gets about 6 pounds lighter during the dive, so you need to release air. Finally, as air expands while ascending, you need to let air out.
How do scuba divers use density?
Divers use substances with high density (ie. lead) to help them sink, and substances with low density (ie. air) to help them float. That way they control their bouyancy.
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.
