Hot-air balloons can rise up into the air because hot air is lighter, allowing it to float up into the sky.
What else can I help you with?
Does helium rise?
yes honey, that's why hot air balloons rise
Will a balloon rise if the air inside is hot?
The heating of the air through the use of a burner is what makes balloons rise.
How high do hot air balloons go up?
they contain helium molecules which are lighter than the air we breath making the balloons rise
How do air balloons lift off from the ground?
Balloons filled with Helium rise because Helium is less dense than normal air. Hot air balloons lift off the ground because heat rises, and when the balloon is full of air of a higher temperature than its surroundings, the balloon will rise.
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.
What source is used to fly hot air balloons?
Wind !... The balloons are filled with hot air, which causes them to rise. They are then at the mercy f the wind direction.
What does thrust have to do with hot air balloons?
This may not help, but I didn't think it had ANYTHING to do with hot-air balloons...
Why were hot air balloons made in 1783?
People think that hot air balloons where made for battles.
What gas is found in balloons that rise to the ceiling?
Helium gas is found in balloons that rise to the ceiling. This gas is less dense than air, causing the balloon to float upward.
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 are hot air balloons able to rise into the air?
Hot air balloons rise because when the air inside the balloon is heated, it becomes less dense than the surrounding cooler air. This difference in density creates lift, causing the hot air balloon to float upward.
Which gas do you use for hot air balloons?
Hot air balloons typically use propane gas as a fuel source for the burner that heats the air inside the balloon envelope. The propane is burned to heat the air, which causes the balloon to rise.
