Mountaineers carry oxygen cylinders with them on high altitude mountains like Mount Everest. This is because the higher the mountaineer climbs the less air there is to breathe.
When you travel in an aeroplane at a high altitude the plane will be pressurized. A cabin air pressure at cruising altitude is lower than air pressure at sea level. At typical cruising altitudes in the range 11 000-12 200 m (36 000-40 000 feet), air pressure in the cabin is equivalent to the outside air pressure at 1800-2400 m (6000-8000 feet) above sea level.
the air becomes rarefied and has a very low oxygen
Mountaineers carry oxygen cylinders at high altitudes where the air is thin and oxygen levels are low to prevent altitude sickness and hypoxia. Spacemen carry oxygen cylinders in space where there is no breathable air available, ensuring they have a supply of oxygen to breathe in their spacecraft or during spacewalks.
At extreme altitudes, the air becomes rarefied and has a very low oxygen concentration. This can lead to a condition known as hypoxia, which is deprivation of oxygen to the brain, which can cause loss of consciousness, paralysis, and death.
Because at great heights ie up mountains the air becomes 'thinner' this means there is less oxygen and so it is harder to breathe. So they carry the oxygen so that they can continue up the mountain otherwise they will be unable to coninue because it is dangerous.
Mountaineers carry oxygen cylinders at high altitudes to supplement the reduced oxygen levels in the air. This helps prevent altitude sickness, improves physical performance, and reduces the risk of life-threatening conditions such as hypoxia and cerebral edema.
It is because at high altitudes the oxygen is not sufficient..........
A climber carries an oxygen cylinder on their back because it helps him/her to breathe easier. On high altitude mountains like Mount Everest the air is so thin it makes it very hard for anyone to breathe without extra oxygen from a cylinder.
Oxygen cylinders are typically larger and heavier than acetylene cylinders due to the higher pressure at which oxygen is stored. Oxygen cylinders may also contain more volume of gas compared to acetylene cylinders.
The higher you go up away from the Earth's surface, the less oxygen can be found in the air and more of gases we don't need to breathe in. So, as the mountaineer goes higher up, breathing becomes harder and your body works slowly, reducing reaction times. By carrying an oxygen tank, the mountaineer can always be breathing the perfect concentration of oxygen they need at all times.
I dont know, not while I've been alive
because the higher you go up a mountains are the less oxygen there is.
