1. Use the altitude air pressure calculator (Links to an external site.) (Links to an external site.)to find the level of oxygen at 15 different elevations. Determine whether the effects altitude has on human body oxygen supply will be fatal, mild or Nil.

No.	Elevation	Summit altitude above sea Level (ft)	Calculate Oxygen available as percent of sea level (20.9%)	Possible negative Effects on body’s oxygen supply. Put ‘X’ where it is true.
				Fatal	Mild	Nil
1	Mt. Everest summit	29,035
2	Mt. K2, China-Pakistan border	28,251
3	Aconcagua, Andes Mountain, Argentina-Chile border	22,841
4	Mt. Denali, Alaska	20,308
5	Mt. Kilimanjaro, Tanzania	19,341
6	Mont Blanc, Alps Mt.	15,781
7	Mt. Whitney, CA	14,505
8	Pikes Peak, CO	14,115
9	Mt. Baldy, CA	12,441
10	Mt. Phillips, NM	11,711
11	Aspen, CO	8,000
12	Mt. Washington	6,288
13	Denver, CO	5,280
14	Mt. Shasta, CA	3,586
15	Golden Gate Bridge, SF	746

Note: At sea level, the standard barometric pressure is 101 kPa, (1013.25 mbar) or (760 mmHg). This means that there is 100% of the oxygen available at sea level. Remember, about 21% of the atmosphere is Oxygen.

2. Based on your computations of oxygen in the above table, climbing which mountains would put a person not carrying oxygen tank at risk?

3. Suppose a commercial airliner is taking you from San Francisco to New York at 12,000 m (39,400 ft) altitude. [Use altitude air pressure calculator.]  

1. What is the amount of oxygen available at this flight altitude as percent of at sea level? ________%
2. In aviation, cabin pressurization is used to create a safe and comfortable environment for aircraft passengers and crew flying at high altitude by pumping conditioned air into the cabin. Based on your calculation in (A) above, can you fly at this elevation without the airliner adjusting cabin pressure? Explain.

[Yes/No]            __________________.
