How high do hot air balloons go up?
they contain helium molecules which are lighter than the air we breath making the balloons rise
What fuel is used in hot air balloons?
Propane. This is what makes the flame that heats the air in the balloon.
What makes balloons go up?
Balloons float up in the air because they are filled with a gas that is lighter than the surrounding air. This gas, often helium or hydrogen, creates a buoyant force that is greater than the force of gravity, causing the balloon to rise.
Why do we need hot air balloons?
It needs hot air because hot air goes up and cold air goes down. Hot air makes it go up.
What are things that go up?
Balloons, airplanes, and rockets are things that go up.

Why do you think hot-air balloons can rise into the air?
Hot-air balloons can rise up into the air because hot air is lighter, allowing it to float up into the sky.

What can you fill up with balloons?

Which makes balloons fly up in the air carbon dioxide helium or hydrogen?
Helium is typically used to make balloons fly up in the air because it is lighter than air and creates lift. Hydrogen is also lighter than air and can be used, but it is flammable. Carbon dioxide is heavier than air and would cause a balloon to sink.
If you trap air in a balloon and put it into warm air will it float?
If the air in the balloon is cooler than the air around it, it will sink. Hot air balloons go up because they weigh less than the air around them.
Why do helium-filled balloons float up in the air?
Helium is lighter than air.
