How do you use buoyancy?
Buoyancy is what keeps a boat floating on the top of the water. Buoyancy is what makes a helium balloon float in the air.
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 a hot air balloon stays in the air?
A hot air balloon can stay in the air because the hot air is less dense than cool air. The hot air that is blown into the balloon causes it to rise and a burner is used to heat the air inside of the balloon to keep it floating.
How does a balloon expand?
when you fill a balloon with air the air makes pressure. the air pressure maximizes the balloon fabric allowing the balloon to expand.
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.
What force makes a hot air balloon rise up into the air?
The upthrust exerted by surrounding air on the balloon.
How does a hot air balloon stop?
There is a handle that you pull to close the vent that blows hot air into the balloon.
Why is an hot air balloon called a hot air balloon?
Because the fire or heating device heats the air in the top section ( the actual balloon ) and hot air rises... so the hot air trapped in the balloon makes the balloon rise :)
What could a pilot do cause the balloon back to the ground?
If a hot air balloon, then stop heating the air. If a lighter-than-air balloon then release some of the gas.
What helps a hot air balloon go higher?
Hot air makes the balloon go higher. That's why it's called a hot air balloon
What kind of energy does a balloon floating in the air have than a boulder a the top of a cliff?
what kind of energy does afloating balloon have
When the balloon is floating high above the ground how could the balloonist make the balloon descend gradually?
the balloonist would turn off the burner, allowing the air inside the balloon to cool down. Hot air rises so as the air cools down the balloon will lose altitude.
