Why do helium balloons rise in air?
The helium balloon rises in air because the density of helium inside the balloon is less than that of the surrounded air that is displaced by the balloons volume. So the balloon is lighter than the surrounding air. Ice cubes float in a glass of liquid water for the same reason.
What gas makes a balloon rise into the air?
Helium. It is lighter than air and provides buoyancy, causing the balloon to rise.
What is the buoyant force of a hot air balloon?
The buoyant force on a hot air balloon is equal to the weight of the air displaced by the balloon. When the air inside the balloon is heated, it becomes less dense than the surrounding air, causing the balloon to rise. The buoyant force allows the balloon to float in the air.
Why would heating the gas in air balloon make balloon rise?
if you mean how the hot air in a hot air balloon makes it rise, its because hot air is less dense than cold air. when cold and hot air meet the cold air sinks thus making hot air left to rise.so when you put hot air in a balloon the air would rise. hope this helps.
What makes a balloon rise?
A balloon rises because it is filled with a gas that is lighter than the surrounding air, typically helium or hot air. The lighter gas creates buoyant force, lifting the balloon off the ground.
How does hot and cold air have an effect on an balloon?
If there is warm air in the balloon, cooler air makes the balloon rise and if there is cold air in the balloon warmer air makes the balloon fall.
How does thermal expansion make a hot-air balloon rise?
It rises because when thermal engery is in the balloon it makes an expansion that makes the balloon fly
Why would heating the gas in a hot air balloon make the balloon rise?
When the gas (air) in a hot air balloon is heated it becomes less dense. This makes the balloon more buoyant so it rises.Because heating the air inside the balloon makes it less dense than the air surrounding the outside of the balloon, so it will rise.
Why do helium balloons rise in air?
The helium balloon rises in air because the density of helium inside the balloon is less than that of the surrounded air that is displaced by the balloons volume. So the balloon is lighter than the surrounding air. Ice cubes float in a glass of liquid water for the same reason.

What is the buoyant force of a hot air balloon?
The buoyant force on a hot air balloon is equal to the weight of the air displaced by the balloon. When the air inside the balloon is heated, it becomes less dense than the surrounding air, causing the balloon to rise. The buoyant force allows the balloon to float in the air.
What force makes a hot air balloon rise?
A hot air balloon rises due to the principle of buoyancy. As the air inside the balloon is heated, it becomes less dense than the surrounding air, causing the balloon to float upwards. This effect is similar to how a helium balloon rises in the atmosphere.

Which force allows a balloon to fly?
The force of buoyancy, which is created by the displacement of air by the balloon, allows it to fly. This force is greater than the weight of the balloon, causing it to rise.
What makes a balloon fly up?
The hot air, inside of it is very light and makes the balloon rise up.
What force brings a hot air balloon to earth after the hot air is let out?
Erm.. no.. i believe its Buoyancy... this force causes u the hot air balloon to rise.. not Gravity..
