If the airplane's cabin is not "pressurized" then it will have low atmospheric pressure. That means the air is thinner. The air is less dense. The molecules in the air are farther apart. At lower altitudes the air is compressed and made denser since the molecules are shoved closer together, and you get more of them in each lung full you breathe. If you blow up a balloon on the ground and then take it 10,000 feet in the air, the air trapped inside the balloon will expand because it wants to match the density of the air around it, and air is less dense the higher up in the atmosphere you go.
P.S. This is why pilots of non-pressurized airplanes wear oxygen masks when they fly high. The air above 10,000 (or 14,000, or something like that) has too few molecules of oxygen for each lungful of air you suck in.
What else can I help you with?
Is the pressure high or low at high altitude?
The pressure is low at high altitudes because the weight of the air above decreases as you move higher in elevation. This decrease in pressure can have physiological impacts on the body, such as lower oxygen saturation.
What is likely to happen if a balloon that was blown up at a low altitude is brought to high altitude why would this occur?
If a balloon that was blown up at a low altitude is brought to a high altitude, it is likely to expand and potentially burst. This occurs because the atmospheric pressure decreases with altitude, causing the gas inside the balloon to exert more pressure on the inner walls as it expands. Since the balloon material can only stretch to a certain limit, the reduced external pressure allows the internal pressure to increase, leading to expansion and possible rupture.
Does wind move from high to low or low to high pressure?
Wind moves from high pressure to low pressure. Air always moves from areas of high pressure to areas of low pressure in an attempt to equalize pressure differences.
What If a flight is made from an area of low pressure into an area of high pressure without the altimeter setting being adjusted the altimeter will indicate?
lower than the actual altitude above sea level.
Does it move from an area of high pressure to low pressure or low pressure to high pressure?
A fluid will move from high pressure to low pressure.
What defines low air pressure and where is low air pressure typically found?
There is low air pressure usually when you are up in a mountain or in an airplane like when your ears pop after you get in an airplane and you are at high altitude your ears do this because the pressure inside your ears and the pressure in the air is not the same. When there low air pressure the air is less dense.
Why do nose bleed at high altitude?
because the pressure is high and temperature is low
Can air pressure falls drastically at high altitude?
Air pressure falls of as one gains altitude. At high altitude the air pressure is very low but it does not "falls drastically", which implies a sudden change.
Why Nose bleeds at high altitude?
because the pressure is high and temperature is low
How does atmospheric parameters affect aircraft's lift and drag force generation while gaining altitude?
Temperature - low temperature gains altitude quicker Pressure - High pressure gains altitude quicker Density - Low density gains altitude quicker
Is the air pressure in a flying airplane greater that outside the flying airplane?
In a commercial airliner flying at cruising altitude, the air pressure inside the airplane is considerably higher than the air pressure outside. The air pressure outside is too low for people to breathe comfortably, so the interior is pressurized.
Is air pressure greater at high altitudes or low altitudes?
It is greater at a lower altitude.
Is the pressure high or low at high altitude?
The pressure is low at high altitudes because the weight of the air above decreases as you move higher in elevation. This decrease in pressure can have physiological impacts on the body, such as lower oxygen saturation.
Is there high or low pressure on top of mountains?
There is lower air pressure on top of mountains compared to sea level, due to the decrease in atmospheric density as altitude increases.
What is likely to happen if a balloon that was blown up at a low altitude is brought to high altitude why would this occur?
If a balloon that was blown up at a low altitude is brought to a high altitude, it is likely to expand and potentially burst. This occurs because the atmospheric pressure decreases with altitude, causing the gas inside the balloon to exert more pressure on the inner walls as it expands. Since the balloon material can only stretch to a certain limit, the reduced external pressure allows the internal pressure to increase, leading to expansion and possible rupture.
How does pressure change with altitude and what factors influence this relationship?
Pressure decreases with increasing altitude due to the decrease in the density of air molecules as altitude increases. Factors that influence this relationship include temperature, humidity, and the presence of weather systems such as high or low pressure systems.
How airplane flies?
differential in wind speed over the wings produces high pressure under the wing and low pressure on top of the wing.
