A plastic bottle gets crushed on an airplane that is landing because-
Outside pressure is greater than the pressure inside the bottle.
Outside pressure is less than the pressure inside the bottle.
Why is the mountain climber (in picture) using bottled oxygen?
Increase in pressure with altitude increases the density of molecules in air
Decrease in pressure with altitude increases the density of molecules in air
Decrease in pressure with altitude decreases the density of molecules in air
This is an unnecessary precaution as pressure is always constant
