An airplane is pressurized to 650 , which is the atmospheric pressure at a ski resort at 1.30×104 altitude.

If air is 21 oxygen, what is the partial pressure of oxygen on the plane?

If the partial pressure of oxygen drops below 100 , passengers become drowsy. If this happens, oxygen masks are released. What is the total cabin pressure at which oxygen masks are dropped?

You are doing research on planet X, and you take your favorite balloon with you. The temperature inside the space station is a carefully controlled 22 and the pressure is 753 . Your balloon drifts into the air lock, which cycles, sending your balloon, which has a volume of 860 , into the atmosphere of planet X.

If the night temperature on planet X is -102 and the pressure is 0.15 , what volume will your balloon occupy assuming that it is very elastic and will not burst?

Express your answer using two significant figures.
