Airplane cabins are pressurized because humans cannot breath at a very high elevation.
Aircraft are pressurized to allow them to fly higher. Without pressurization, the amount of oxygen in the air would not be sufficient for humans to breathe.

Can you boil water on a airplane?
Yes. Airplane cabins are usually pressurized to around 5,000 feet. So imagine you are just boiling water at 5,000 feet.
Why must airplane cabins be pressurized?
Because at altitudes above 10,000 feet there is not enough air for humans to breathe. Aircraft cabins are pressurised so that the internal pressure is equal to that at about 7,000 feet.
Why is an airplane cabin air pressurized?
At altitudes above 10,000 feet there is not enough air for humans to breathe. Aircraft cabins are pressurized so the pressure is equal to that at about 7,000 feet. Commercial airliners fly at altitudes up to 40,000 feet.
Why are submarines cabins pressurized?
To keep water from leaking in.
What was the breakthrough technology introduced by Boeing 307 stratoliner in 1940?
Pressurized Cabins
What happens if an airplane is not pressurized?
death happens if the airplane is over 20000 feet
How are airplane cabins pressurized?
There are air pumps in the outer jacket of the jet engines. Outside fresh air is taken in, compressed by pistons, and forced into ducts that send it into the cabin. The cabin is tightly sealed with carefully calculated exhaust. This allows the small air pump to keep the cabin pressurized. The cabin heaters are usually part of the pressurization system.
How are air craft cabins pressurized?
Pressure is created in the engines and/or APU as "bleed air" and enters the cabin.
Why don't helicopter cabins have to be pressurized?
Helicopters don't generally fly high enough for cabin pressurization to be necessary.
Why air crafts at high altitude must have pressurized cabins?
Mostly not enough oxygen in the air at the low pressure up there.
Why do passenger aircraft have pressurized cabins?
To allow passengers to breathe sufficient oxygen, needed to survive, even in high altitudes.
Is packing soda on an airplane possible?
yes, the cabin and cargo holds are pressurized.
