What happens when your airplane takes off from an airstrip on the ground and rises 30000 feet into the sky what happens to the air pressure on the outside of the airplane?
Atmospheric pressure is caused by the weight of air above the measurement point. At 30,000 feet in the sky, the air pressure on the outside of the airplane will be much lower than it was nearer the ground.
Why does water boil at a lower temperature on a mountain than sea level?
The boiling of any liquid is tied in to the atmospheric pressure, in an open system. Every liquid has it's own vapor pressure, that is the balance between the vapor and liquid phase. When atmospheric pressure decreases, the vapor pressure increases since now there is greater space for the molecules of the liquid to come into vapor phase. At higher altitudes, the atmospheric pressure is lesser, that is, the air is thinner. Thus the liquid can attain higher vapor pressure faster and boil at a lower temperature.
What would held you float safely to the ground from an airplane?
A parachute would help you float safely to the ground from an airplane.
What makes an airplane lift off the ground?
An airplane lifts off the ground because of the upward force created by the difference in pressure from the upper and lower part of the wing. The air travels faster over the top of the wing than the bottom of the wing because of the wing shape. This creates a low pressure on the top of the wing and high on the bottom. This can be explained better by understanding Bernoulli's Principal. The pressure difference causes and upward force on the wing which creates lift which allows the plane to lift off the ground.
What force is activated because of the mass of the airplane and works to pull an airplane to the ground?
Gravity

Is the atmospheric pressure equal everywhere?
No - that's why we get winds. Winds are caused by air flowing from high-pressure areas to low-pressure zones. AVERAGE atmospheric pressure at ground level is 14 psi. (pounds per square inch)
Why does a fountain pen leak in an airplane?
there is less pressure above the ground so the ink inside it burlge outside and flow in airplane......
In general as elevation increases from the ground up what happens to atmospheric pressure?
Pressure decreases. This is because atmospheric pressure is a measure of the weight of the atmosphere weighing down. If you are high in the atmosphere, much of the atmosphere is below you so the pressure from above will be very small.
Why do your ears pop when your airplane takes off?
As the plane climbs, the pressure drops, even in a pressure cabin. The pop is your ears equalizing from ground pressure to altitude pressure.
Why barometric condenser is installed at least 34 feet 10.4 meters above the ground?
Because this high (which is the height of a lliquid column equivalent to the atmospheric pressure) will compensate the atmospheric pressure autside of the system under vacuum
Will helium balloon pop on airplane?
On modern airplanes no, because the cabin is pressurised to the same atmospheric pressure as on the ground. If the balloon was on the outside of the plane, and the atmospheric pressure at that altitude were low enough, then yes, the balloon would pop.
What is the name of an airplane driving on the ground?
Moving an airplane on the ground is called 'taxiing'
What effect do you think that has no air pressure on the ground?
Without atmospheric pressure, water will boil to vapour, so as our blood and body would explode. Pressure is what that keep water in liquid and solid state on earth.

Barometric pressure ground level?
Atmospheric pressure varies with altitude and air density. Average sea-level pressure is 101.325 kPa (1013.25 mbar) or 29.921 inches of mercury (inHg) or 760 millimeters of mercury (mmHg).
Why can you not breathe 3000 feet off the ground?
This Is Because the atmospheric pressure of earth is always acting.We did not feel this because our blood pressure is equal to atmospheric pressure.It is perfectly possible to breath at this altitude. Mt. Everest, which is much higher than this, has been climbed without any breathing aids.
