The density of air in the stratosphere is significantly lower than at lower altitudes due to decreasing temperature with altitude. On average, the density in the stratosphere is about 1/1000th of the density at sea level.
Air density - at least, the average air density - pretty much depends on the altitude. I suggest you look up the altitude of both places (you can probably find it on the corresponding Wikipedia articles); the place with the lower altitude should have a greater air density.
The vapor density of air is the ratio of the mass of a certain volume of air to the mass of an equal volume of a reference gas, typically hydrogen or dry air. It is used to compare the density of a gas to that of another gas or to the average molecular weight of air. The vapor density of air is approximately 1.29, meaning that air is slightly heavier than the reference gas hydrogen.
That depends on what fills the remainder of the bottle. If it is air, the average density of your bottle will be less than the density of the liquid.That depends on what fills the remainder of the bottle.

They have ballast tanks that can be filled with air for buoyancy.Answer:Floating or sinking in water is related to the density of the entire enclosed volume of the submarine. Obviously if the metal in a submarine were compressed into a ball it would sink as its density would exceed the density of water. However the average density of a submarine (metal skin, interior equipment and air) is less than that of water and it floats. To dive the air in the ballast tanks is compressed or allowed to escape increasing the average density and it sinks. Replacing the air in the same tanks decreases the density and it floats once more.This is somewhat like a hot air balloon. The material in the balloon would not float in the air, however once the balloon is filled with hot air, the average density decreases and the balloon rises.
Hot air balloons are powered by the flame from a propane burner that heats up the air inside the balloon, which lowers the density of the air inside by heating it up and accellerating the particles. Lower density (hot) air will rise above air with higher density (the air outside) which is why they have a height limit, as the average density of air goes down the higher you go.
Finding the average density of a liquid allows us to determine its mass per unit volume, which can be useful for various applications in science and engineering. This information is particularly important when dealing with mixtures or solutions where different liquids are present, as the average density helps us understand the overall density of the combined substances.
The density of heated air is less than the density of cooler air.
The moon's average density is about the same as the density of mantle of the Earth.
you would have to deacrease the density. By doing so, you can float. I don't know bout constant level, but because the air in the balloon is more dense than outside air, the balloon will sink in air. p.s. i know you s.j.v students are probably reading this :)
Hot air has density less than the air surrounding the balloon. When the average density of the balloon filled with hot air is less than the density of the air outside upthrust is more than the weight of the balloon. therefore it keeps on rising up till the upthrust becomes equal to the weight of the balloon.
