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?
Balloons float when they are full of air because the helium or air inside is less dense than the surrounding air, creating buoyancy. When they are deflated, the balloon is denser than the surrounding air, causing it to sink rather than float. This is due to the principle of buoyancy and the difference in density between the balloon and the air.
Why do balloons float in the air?
Balloons float in the air because they are filled with a gas that is lighter than the surrounding air, such as helium or hot air. This creates a buoyant force that allows the balloon to rise and float.
Why do bubbles float?
Bubbles float because they are filled with gas that is lighter than the surrounding air. This causes them to rise and float on the surface of liquids or in the air.
What must happen for a balloon to float in the air?
For a balloon to float in the air, it must be filled with a gas that is lighter than the surrounding air, such as helium or hot air. This creates a buoyant force that allows the balloon to rise and float.
Why can the lantern float in the air?
The lantern can float in the air because it uses a heat source, such as a flame, to heat the air inside the lantern. When the air inside the lantern is heated, it becomes less dense than the surrounding air, causing the lantern to float.
Does any train float on air?
No a train does not float in the air, no train does.
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.
Why does a swimming float float?
Because it has air in it. Air weighs less than water therefore air floats.
What makes balloons float when they are full of air but not float when they are deflated?
Balloons float when they are full of air because the helium or air inside is less dense than the surrounding air, creating buoyancy. When they are deflated, the balloon is denser than the surrounding air, causing it to sink rather than float. This is due to the principle of buoyancy and the difference in density between the balloon and the air.
How does a barge float?
It will float because water has more density than air and barges have air in them
Why do balloons float in the air?
Balloons float in the air because they are filled with a gas that is lighter than the surrounding air, such as helium or hot air. This creates a buoyant force that allows the balloon to rise and float.
Where in the atmosphere do hot air balloons float?
Hot air balloons float because hot air displaces cool air in the atmosphere
Why don't mostsubstance float in air if they float in water?
It is waters greater density than air that allows some substances to float on water.
Why does a helium balloom float in air?
Helium is lighter than air. so balloons filled with helium will float in air
How did david blaine float in the air on tv?
