Why do mountaineers and divers carry oxygen cylinders with them Class 6?
Mountaineers carry oxygen cylinders while going to high mountain peaks because altitude increases as they climb the mountain. The amount of oxygen decreases as the altitude increases. … The altitude which is also called the death zone altitude is twenty six thousand feet and above.
Why do scuba divers carry oxygen cylinders with them?
Sea divers carry oxygen gas cylinders along with them because there is no free oxygen in the sea water since the little dissolved oxygen present in water can’t be used for breathing by divers. It can be used only by aquatic animals.
Why does a deep sea divers and mountaineers carry oxygen cylinder on her back?
When we go deep into the earth or sea,the oxygen level decreases. So,deep sea divers carry oxygen cylinders in their backs so as to receive oxygen. If they do not carry them,they do not get oxygen and there is a chance even to die. … So,they must carry them as they go deep into the sea.
Why do mountaineers carry oxygen cylinders with them Boyle’s Law?
Mountaineers have to carry oxygen cylinders with them to restore normal breathing because at high altitude the density of air is less. That means less oxygen molecules occupy the same volume. Therefore, oxygen in air becomes insufficient for normal breathing.
Why do mountaineers carry oxygen cylinders with them Class 7?
Mountaineers carry oxygen gas cylinders with them because as altitude increases, the amount of oxygen level in the atmospheric air decreases. Mountaineers carry oxygen cylinders with them because when climbing mountains, as the altitude rises the amount of oxygen in the air decreases.
Why mountaineers carry oxygen cylinders with them at what height do they need oxygen cylinders?
It is because when they climb mountains, as altitude increases, the amount of oxygen level in the atmospheric air decreases as trees are not found at higher altitudes.
Why do mountain climbers at high elevations use oxygen tanks to help them breathe?
Why do mountain climbers at high elevations use oxygen tanks to help them breathe? … The atmosphere is less dense at higher elevations so there is less oxygen available. Oxygen is heavier than the other gases in the atmosphere and sinks to lower elevations.
What is the bends in the ocean?
Decompression sickness: Often called “the bends,” decompression sickness happens when a scuba diver ascends too quickly. Divers breathe compressed air that contains nitrogen. At higher pressure under water, the nitrogen gas goes into the body’s tissues. This doesn’t cause a problem when a diver is down in the water.
