to help with breathing in hot temperatures or when gas or dust is released
Because it is too hot for them so they need cylinders of oxygen to breathe
mountaineers carry oxygen cylinders because if they have breathing problem if they can bhreath with the the help of the oxygen cylinders
They dont 'only' carry oxygen cylinders, they also have other gear with them.
You can buy oxygen cylinders online at http://www.trishir.com/products-details.asp?POID=251 They offer many cylinders of small,medium portable cylinders You can buy small oxygen cylinders at www.oxygenmobility.com For more details call 800-716-6674.
They have to carry oxygen cylinders with them as it allows them to breath at high altitude. The temperature also decreases as we go higher and higher.
Climbers carry oxygen cylinders because there is less usable oxygen at the highest elevations. The ability to function is greatly reduced without the use of supplemental oxygen.
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.
Compressibility. A lot of gas is forced into the cylinders.
the air becomes rarefied and has a very low oxygen
Mountaineers carry oxygen cylinders when climbing mountains of extreme altitude like Mount Everest. This is because the higher you climb the less oxygen there is to breathe.
Air contains 20% oxygen, When you go up a mountain the air is "thinner" and there is not enough oxygen so mountaineers breath oxygen from cylinders so that each breath has more than 20% oxygen, This helps them function at altitude. Divers DO NOT Carry Oxygen cylinders with them, they breath from cylinders containing compressed AIR. When you dive the "thickness" of the air increases, at 10 meters you are breathing air at TWICE atmospheric pressure. At depth the Oxygen becomes toxic. If you were to dive on pure Oxygen you could die if you went as deep as 10 meters.
Because lungs are not adapted to absorb oxygen from the water.
Because they find themselves in environments of little or no oxygen, and oxygen is essential to life.
There are four oxygen sensors one on each exhaust manifold or bank of cylinders and one after each cat for both banks of cylinders
leaking oxygen cylinders and liquid oxygen systems in the immediate area
They carry the oxygen cylinders because they are needed to breathe. On a high mountain the air is so thin it is very hard to breathe so this oxygen is there lifeline.
To date (end of 2017) there has been208 climbers who have climbed Mount Everest without using oxygen cylinders (tanks) and 8,098 who have used oxygen cylinders.
A person can get the supply of oxygen for artificial respiration from the cylinders attached to the machines.
Oxygen is an element. it will support combustion, and has the industrial color code of Green in cylinders.
Oxygen is used in the process of respiration.It is used as hydrogen peroxide.Oxygen is in oxygen cylinders.Water has oxygen atom attached to hydrogen atoms.Oxygen is used in making detergents.
So that they may breath underwater.
Climbers carry oxygen cylinders on high mountains because there is less oxygen than there is at sea level.
The higher you go, the less oxygen there is in the air (you could compare this to a pool of water; the deeper you go, the more dense the water becomes and vice versa). Mountaineers would carry oxygen cylinders to compensate for the lack of oxygen in the altitudes they climb up to.
The spacesuits protect them, also they use oxygen cylinders.
Gas can be compressed easily.
Such cylinders are made in a variety of capacities.
