Imagine you are planning to climb Mt. Everest. You
want to climb to the summit where the air pressure is 0.33 atm and the temperature
is -15°C. In order to breathe safely and comfortably at the summit you plan to
bring a supply of oxygen with you. You plan to bring a 3 L tank of oxygen. If
you wanted to stay at the summit for 15 minutes, breathing an average of 15
breaths per minute assuming each breath is 4.5 L , what would be the minimum
pressure to which you would need to fill the tank at the base of the mountain
where the temperature is 20°C?
