A balloon does not float with your breath because the air you blow into it is denser than the surrounding air. To make a balloon float, you need to use a lighter gas, such as helium, which is less dense than the surrounding air and creates enough lift to keep the balloon suspended.

Why heating the air allows a hot air balloon to float?
Heating the air inside the balloon makes it less dense than the surrounding air, causing the balloon to float. As warm air is lighter than cool air, the balloon rises because of the difference in densities. This creates an upward force, known as buoyancy, that allows the balloon to float.
Does a balloon float or sink on water and why?
A balloon filled with air will float on water because it is less dense than water. The buoyant force acting on the balloon allows it to float.
Can you make a balloon that float in air?
Yes, a helium-filled balloon will float in the air because helium is less dense than the surrounding air. When filled with helium, the balloon experiences a buoyant force that causes it to rise and float.
Why does an air balloon not float?
A hot air balloon floats because the air inside is heated, making it less dense than the cooler air outside. This creates a buoyant force that lifts the balloon. If the air inside the balloon is not heated, it will not be less dense than the surrounding air, and the balloon will not float.
In a hot air balloon air is heated by a flame Explain how this enables the balloon to float?
Heating the air inside the balloon makes it less dense than the surrounding air, causing the balloon to float upwards. As the air inside the balloon cools, it becomes denser and the balloon descends. The pilot can control the altitude by adjusting the temperature of the air inside the balloon.
Why can't a hot air balloon float in outer space?
A hot air balloon requires air to generate lift. In outer space, there is no air or atmosphere, so there is nothing for the hot air balloon to displace to generate lift, causing it to be unable to float.

How does a helium balloon float but not a balloon filled with air?
Helium is lighter than air, so it creates lift in the balloon. When you fill a balloon with air, the air is denser than the surrounding air, so the balloon doesn't float.
Why do balloons filled with air not float?
Because air is not as dense as helium filed gallons so they won't float
Why do hot air balloons float in the air?
Hot air balloons float in the air because the air inside the balloon is heated by a burner, causing it to be less dense than the surrounding cooler air. This temperature difference creates a buoyant force that lifts the balloon. The balloon will continue to rise until the temperature inside equalizes with the outside air, allowing it to maintain a stable altitude.
Can dry ice float a hot air balloon?
No. Dry ice is frozen carbon dioxide, which is heavier than air, so wont float a balloon.
If you wanted to make a balloon float in the air which gas should you use to fill the balloon?
Helium is commonly used to fill balloons to make them float in the air. Helium is lighter than air, so when it is inside a balloon, it provides buoyancy and causes the balloon to rise.
How does heilum make a balloon float?
When helium is added to a balloon, it decreases the overall density of the balloon compared to the surrounding air. This causes the balloon to float because the buoyant force exerted by the helium is greater than the force of gravity acting on the balloon. This buoyant force allows the balloon to rise in the air.
