Scuba divers require increased air pressures in their air tanks while diving because the pressure on their bodies increases.
What else can I help you with?
How can a scuba-diver breath underwater?
From a regulator attached to a scuba tank.
Why scuba diver wear oxygen tank?
so they can breath underwater
A diver uses it to help him breathe while under water?
aqualung, snorkle, SCUBA tank
What does a diver use to breathe underwater?
A SCUBA (self-contained underwater breathing apparatus) tank
How is the frog like a scuba diver?
Well, it needs oxygen like a human scuba diver but it lasts a pretty long time underwater just like a human would if he used an oxygen tank.
What has gas pressure?
Anything pressurised with gas - an auto tire for example, or a scuba diver's air tank.
What type of gas is in a scuba diver tank?
Air...Sometimes Have Abit Of Oxygen In..But Most Of The Time Just Normal Air.
What does a diver use to help them breathe underwater?
The diver uses an air tank, which is a tank filled with compressed air. It has a hose that goes from the tank to the mouth, which is held in the mouth by a 'mouth piece'. The tank has a regulator that allows the pressure in the tank to be regulated down for normal breathing.
Do you need to be a certified diver to have a dive air tank filled?
no
What do you call a person who works underwater?
With a tube = Snorkling With an air tank = SCUBA With a tube and metal helment = Hard Hat Diving.
Why do you need oxygen cylinders when you go scuba diving?
The simple answer is ... you don't. A majority of scuba dives use compressed air in the cylinders. Therefore you don't need "oxygen" cylinders. HOWEVER, if you are a diver that is diving on Nitrox, in which divers change the amount of oxygen vs nitrogen in their air, then your tank needs to be "oxygen clean" because you are putting oxygen in first, then nitrogen.
Is there scuba masks with oxygen in them?
Scuba masks do not contain oxygen. Instead, scuba divers rely on a separate piece of equipment called a tank or cylinder to supply compressed air or a breathing gas mixture for underwater breathing. The scuba mask's purpose is to provide a clear field of vision and to create an airspace for the diver's eyes and nose while underwater.
