At the summit of Mount Everest there is approximately 33% of the oxygen that is available at sea level.
At the summit of Mount Everest there is approximately only 33% of the oxygen that is available at sea level.The higher you climb any mountain the less oxygen there is to breathe. This is why climbers carry oxygen cylinders on there backs to help them breathe more easliy.The proportion of Oxygen to other elements is actually very similar to sea level, but the total amount of air or atmosphere is only about one-third that of sea-level, so there is about one-third as much oxygen as there is at sea level.
I would say the one thing you need to reach the summit of Mount Everest is luck. There are many things that can destroy your summit dream such as: Bad weather, avalanches, illness, faulty equipment, willpower, accident and much more.
Sleeping in any position on Mount Everest is difficult but I very much doubt you would sleep feet pointing towards the summit. Most would try and sleep on their side or with their head upwards towards the summit.
The boiling point of water changes with altitude. While it boils at 100C at sea level, at the summit of Mount Everest water would boil at a lower temperature of 72C.
It is harder to breathe on the summit of Mount Everest than at sea level due to the lack of oxygen. The higher you climb upwards the less oxygen there is, you enter the death zone where the thin air is.
The air at the summit of Mount Everest is thinner that at Base Camp. It is that thin 99% of climbers use supplementry oxygen to help them breathe.
well i just got back from my expidition it was so much fun 3 people out of my 7 teamates made it (including me) the 4 others came down with HAPE idk about every body else all i know is everybody should climb Everest the summit is AMAZING its the best thing i`ve ever done! wait about 2,000 people have made it to the summit!^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^-Everest Climber
two Reinhold Messner and Peter Habeler, they climbed to the summit with much difficulty. Link for the story below.
There is snow all the way up to the summit but over the years climbers have said there is not as much snow there as there used to be.
If you took a air horn to the summit of Mount Everest I very much doubt you would have the energy or enough deep breath to blow it.
None, there is air at the top of Everest and that air has just as much O2 in percentage terms (20%) as the air at sea level. The problem is that the pressure of the air at the top of Everest is much much less (4.89 psi) than the pressure of the air at sea level (15.48 psi). This means that in each breath you take there is less O2 in comparison to a lung full of air breathed in at sea level, you will need to take 3 breaths on the top of Everest to get as much O2 as one breath at sea level,
Although the summit of Everest is at a higher altitude, K2 is a much more difficult and dangerous climb, due in part to its more inclement weather and comparatively greater height from base to peak.
