How 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. This gas, typically helium or hydrogen, creates buoyancy, causing the balloon to rise and float.
What is added to balloons and hot air balloons?
Balloons can be filled with air (don't float), or with hydrogen or helium (float because the gas is less dense). Hot air balloons use burners to heat the air so that it becomes slightly less dense than the cooler air around it, providing some lift.
Why do baloons float in air?
Balloons float in air because they are filled with a gas that is lighter than the surrounding air, usually helium or hydrogen. This creates a buoyant force that pushes the balloon upward, causing it to float.
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.
How do helium balloons float in the air?
Helium balloons float in the air because helium is lighter than the surrounding air. This causes the balloon to be buoyant and rise upwards.
How do balloons float in the air?

Does hydrogen make balloons float?
Yes, hydrogen gas is lighter than air and can make balloons float. However, hydrogen is highly flammable and can be dangerous, so it is not commonly used today. Helium is a safer alternative for making balloons float.
How do you know hydrogen gas is lighter than air?
Balloons filled with it float in air
Why do balloons only float with helium?
Balloons filled with helium float because helium is lighter than the surrounding air, creating a lifting force. This is known as buoyancy. Regular air-filled balloons are denser than the surrounding air and do not float.
What is added to balloons and hot air balloons?
Balloons can be filled with air (don't float), or with hydrogen or helium (float because the gas is less dense). Hot air balloons use burners to heat the air so that it becomes slightly less dense than the cooler air around it, providing some lift.
Which balloon can float the longest?
Helium balloons can float the longest because helium is lighter than air, providing buoyancy. Other gases like hydrogen can also make balloons float, but helium is safer as it is non-flammable.
Why do baloons float in air?
Balloons float in air because they are filled with a gas that is lighter than the surrounding air, usually helium or hydrogen. This creates a buoyant force that pushes the balloon upward, causing it to float.
Where in the atmosphere do hot air balloons float?
Hot air balloons float because hot air displaces cool air in the atmosphere
When balloons are filled with this they are lighter than air?
Hot air, hydrogen or helium are lighter than cold air.
Is it helium in happy birthday balloons?
Yes, party balloons that float are filled with helium. Helium is used because it is lighter than air, causing the balloon to float upwards, but safer than the alternative hydrogen, which is explosive.
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 is hydrogen used to inflate hot air balloons?
Hydrogen is not used to inflate hot air balloons. Just regular air is used which is then heated to make the balloon more buoyant as hot air weighs less than cold air. Hence the name hot air balloons.
