Air is a mixture of different gases but the most notable of these are Nitrogen, Oxygen and Carbon Dioxide.
As you heat any matter you increase the kinetic energy the particles of that matter have. An increase in kinetic energy means that the particles move more and take up more space. This is called lowering the density.
The effect of this is to have less particles per unit area which, therefore, means that each unit area will have significantly less mass than the same unit area of cooler air.
Things with lower density will float on top of things with higher density therefore warm air will float on cold air.
Air also floats on water due to the differences in density.
As air cools it will sink back down due to the increase in density and therefore increase in mass per unit area. This is the basis for convection currents.

What makes balloons float when they are full of air but not float when they are deflated?
When balloons float they have helium in it. Helium is not air, but a gas. It's lighter than air, which makes it float.
Why do things float in the air?
things float in air because of density
Why do hot air balloons float in the air?
Hot air rises and the fire in the hot air balloon wants to go up and float in the air and since it's can't escape the balloon the fire just brings the balloon with it to float in the air
How does a flame enable a hot air balloon to float?
Because it heats the air and of course the hot air will rise above the cold air causing it to float!
Why doesnt a balloon float with your air?
The air from your lungs has the same density as the air in our atmosphere. As a result a balloon inflated by a human using their lungs is unable to float.

Does any train float on air?
No a train does not float in the air, no train does.
Why do things float in the air?
things float in air because of density
Is ice less dense than air?
If it were, it would float in air. Does it float in air? There's your answer.
What is the cheat code for float in air in pokemon yellow?
Float On Air 010a13d7
What makes floats float?
The float has air in it.
Can balloons float from the air out of your mouth?
Only in water. The air from your mouth is the same density as the air in the room- they will not float in air.
Does helium float or sink in air at room temperature?
Helium is lighter than air. So it will float in air.
Why does a swimming float float?
Because it has air in it. Air weighs less than water therefore air floats.
How does a barge float?
It will float because water has more density than air and barges have air in them
Where in the atmosphere do hot air balloons float?
Hot air balloons float because hot air displaces cool air in the atmosphere
Why does a helium balloom float in air?
Helium is lighter than air. so balloons filled with helium will float in air
