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.
United states main export?

What are some examples of lighter than air vehicles?
-- blimp -- Zeppelin -- dirigible -- hot-air balloon
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?

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.
What is the difference between lighter than air and heavier than air vehicles?
Heavier than air vehicles, such as jet airplanes, are heavy and cannot easily float without propulsion. Lighter than air vehicles, such as a glider, are light enough to glide without propulsion Lighter-than-Air vehcicles means that the vehicle gets its Lift from its bouyancy. Regular aircraft get their lift from the wings due to its forward motion through the air. Gliders do not have propulsion but their wings are very long and produce enough lift to keep them flying.
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 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.
