As you airplane taker off from an airstrip on the ground and rises 30,000 feet into the sky what happens to the air pressure on the outside of the airplane ?
Answers are
Air pressure decreases
Air pressure increases
Air pressure stays same
more information is needed
If the atmosphere gets thinner, what do you think happens to the air pressure outside the airplane?
A. The air pressure decreases
As an airplane takes off from the ground and gains altitude, the air pressure on the outside of the airplane decreases. This happens because air pressure is directly related to altitude.
To understand this phenomenon, you need to know about atmospheric pressure. The Earth's atmosphere is made up of a layer of air molecules, which exert a force called atmospheric pressure. At sea level, the weight of the air above us creates a high atmospheric pressure. As we ascend into the atmosphere, the amount of air molecules above us decreases, resulting in lower atmospheric pressure.
At an altitude of 30,000 feet, the air pressure is significantly lower compared to the pressure at sea level. This decrease in air pressure affects the outside of the airplane, as it is exposed to the surrounding air. On the inside of the airplane, however, the cabin is pressurized to maintain a comfortable environment for passengers.
To summarize, as an airplane takes off and reaches a high altitude like 30,000 feet, the air pressure on the outside decreases.
