Density at 12,000 feet (or 3658 m), is 0.05302 lbm/ft^3 (or 0.8491 kg/m^3).
hi! kinda a big science nerd here. As the altitude increases the ground temp. gets colder . take mount Everest for example the higher up you get the closer you are to the sky where precipitation takes place there for you lack oxygen and heat.
The density of air decreases as the bubble rises, since the bubble can increase in size as it rises. A scuba diver needs to release air from her lungs when rising from a depth for this reason. The density of air inside a Japanese fishing net float (a hollow glass sphere) would not change substantially. Changing its temperature would not change the density, only the pressure, since the same number of molecules are involved.
Rarefaction is the diminution in the density of something, especially air or a gas.
Similarities' Both are matter. Differences: Density
Desert air usually has a very low moisture content. Air above a lake would be much more humid.

The air has the weight of all the air above it pressing down on it. this compresses the air increasing its density. So air at sea level is more dense than air on the top of the mountain, since the air on the mountain top has less air above it pressing down.
At ground level its density is less than the air around it, so it rises, as the altitude increases air density decreases, when the density of the balloon and the air are equal it stops rising.
The air density in any given place depends on its height above sea level and also varies from day to day due to variations in weather patterns.
Density always increases as altitude decreases. So the air density below sea level will be greater than the air density at sea level.
The atmoshperic pressure at 18,000 feet above sea level is 280 mm Hg.
Air density is the mass of air per unit volume, which changes by temperature, humidity, and elevation. Changes in air density will change its pressure. At mean sea level and 20°C, air has a density of approximately 1.2 kg/m3.
It is not, air pressure is greatest at sea level. This is because the air pressure is caused by the weight of the air above you and at sea level the depth of the air column above you is at its maximum.
No, a Mirage is an illusion created by the refraction of light through air of varying density. A heat inversion is a ground level layer of warm air is trapped under a layer of warmer air, which is the opposite of the normal situation where ground level air is warmer than the air above.
At sea level, air has a density of approximately 1.2 kg/m3.
= What is low air density? = well, high or low are relative concepts. Normally the standard air density of the air is defined as the density of the air at 15ºC and at sea level pressure (standard conditions), what give a value of 1,225kg/m3. This way, we can talk about high or low air density related to the standard value. Air density depends on temperature and pressure. The colder the temperature the higher the density is, and the higher the height in the atmosphere the lower the density becomes. In the Everest peak, e.g., air density can be lower than 0,5. Meanwhile in the Antarctica (at sea level) the density could reach values higher than 1,5.
an example of density is like when you are in an airplane the air outside has less density from when you are at sea level because the air particles spread out when air is less dense.
