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.
How high do hot air balloons go up?
they contain helium molecules which are lighter than the air we breath making the balloons rise
Why do hot air balloons float up?
Magic...
Why do balloons float up into the air?
At a hot air balloon festival, hot air balloons slowly fill and then rise majestically in the predawn sky. These hot air balloons fly because of two fundamental principles of physics: the ideal gas law and Archimedes's principle.
What are examples of matter changing volume but not changing the mass?
When air is heated, that volume of air expands (which is why hot air balloons go up). The hot air has changed in volume, but it is still the same mass.
What are hot air balloons?
Hot air balloons are a hobby for people that can afford them. They require crews of several people to chase the balloon and pack it up for the next launch.
What is the element used to blow up balloons?
Gases used are: air (and hot air), helium.
How do hot air balloons use air to fly?
Hot air balloons use the fact that hot air rises as a way to make balloons fly. When the air inside the balloon is heated, it rises, and this creates lift which is used to make the balloon fly.
What are some good things to write about hot air balloons?
You could write about the history of hot air balloons, the physics behind how they work, different designs and shapes of hot air balloons, or personal experiences and stories from hot air balloon rides.
Which force allows hot air balloons to fly?
Hot air balloons fly due to the principle of buoyancy. As the air inside the balloon heats up, it becomes less dense than the surrounding cooler air. This difference in density creates a lifting force that allows the balloon to float in the air.
Where do hot air balloon fly form?
Hot air balloons can pick up and fly from just about anywhere. As long as the surface is flat a hot air balloon can fly from it.
What fuel is used in hot air balloons?
Propane. This is what makes the flame that heats the air in the balloon.
