things float in air because of density
Yes. For every fluid, there are things that float in it ... they just have to be things that are less dense than the fluid. That's how stones float in mercury, logs float in water, and hot balloons float in air.
Yes, in fact small things like bacteria, dust, etc. float in mid-air.
There is NO property of water that allows things to float. Floating in not a property of a substance. It is the difference in density of two objects that allows one to be buoyant when surrounded by the other. This a balloon can float on air, A steel ship can float on water and oil can float on water.
No, it's the air volume on each item. For example, a balloon filled with air will surely float on the water, but a ballon filled with water will not float. That's because there is no air in the second one and that makes it even heavier.
The only things that "float" in air, are things that are lighter than air, and this is because they displace a quantity of air that weighs more than the thing that is floating. This is also true of things that float in water or any other fluid. As for heavier-than-air things that "float" (fly), these are kept aloft by the motion of air, or by the motion of the thing through the air, which amounts to the same thing. In either case, air is passing the flying thing (for instance, an airplane wing) above and below it, creating low pressure above and high pressure below, thereby lifting the thing off the ground. This works only for things that are aerodynamically correct, and these are called airfoils - an airplane wing, a helicopter rotor and a kite are common examples.

I suspect that "flow" is meant to also be "float", but even with that substitution, it just changes the question from nonsensical to counterfactual.Most things that float in water do not float in air.
There are many things that make you float such as a bin or large container turned upside down. The best things that make you float are things with air trapped inside them. These things may be large empty water containers from a water dispencer or lots of bubble wrap or even a coat that has air in the lining.
The force that makes things float is called buoyancy.

things float because they are less denser then the water. second things do not float, the molecules from the water support the molecules from the thing on the water. that is how something heavy can float. it just has to be boyent meaning it is spread out enough so there is more water molecules to hold it up. if you mean in the air it is the same concept.
Helium is lighter than air, hence it will rise up in air, making things float up in the air.
When you breath out under water, you are releasing the air from your lungs. Air is far less dense than water, which is why things that are filled with air float. So if you breath in, and then go under water you will float toward the surface. However, if you breath out and release that air in your lungs, you lose the buoyancy that the air was giving you. Thus causing you to sink...
