What are the controls of a Hot air balloon?
Flame on - gives you more hot air to go up. Flame off and you will gradually go down and if you want to speed this up you can open a valve at the top of the balloon to let the hot air out faster. As to where you are going that is up to where the wind takes you. However where winds may be blowing in different directions at different heights you can ascend or descend to take advantage of these and get some steerage.
Why air balloon come down after some time?
Hot-air balloons function on the principle that warm air rises, and the balloon mechanism holds onto hot air to ascend. Despite this, the hot air can't stay in the balloon forever, the opening at the top of the balloon allowing a slow and steady flow of the hot air out of the balloon and a gentle descent to the ground.
Is a hot-air balloon buoyant?
Yes, hot air balloons are less dense and therefore buoyant ============================================ Hot air balloons are buoyant to the extent that the weight of the hot air in the balloon is lighter than the free air. When the difference is more than the weight of the balloon and its contents it will be buoyant and will ascend.
What was necesary for the hot air ballon to be succesfull?
A hot air balloon needs to carry a means of producing more hot air to keep the envelop inflated and lifting in flight. Otherwise, as the initial hot air cools, so the balloon will descend to the ground.
How do they make hot air balloons descend?
I think you slowly decrease the amount of hot air you're using to lift the balloon. If I'm wrong, I hope someone will correct me.
What gas is used for a hot airballoon?
I am fairly sure that hot air balloons use normal air. They rely more on the idea of bouyancy rather than using specal gases, such as helium. The hot air inside of the balloon is more bouyant than the cold air outside of the balloon. So that makes the balloon ascend till the temperature of the air inside of the balloon is equal to the temperature of the air outside of the balloon. Then as the air inside the balloon gets colder, the balloon starts to descend.
How is the descend and the ascend of a submarine controlled?
By pumping water or air into the ballast tanks.
Why does a change in density of the air make the balloon ascend?
A gas of low density has the tendence to ascend.
What does a hot air balloon use to make the balloon go down?
Hot air balloons go down by releasing the hot air in the balloon. Normally you just let the air inside cool and descend slowly. You release hot air only if you wish to descend more quickly.
What is an air bounce?
An air bounce is a throw of a frisbee at a downward angle causing the frisbee to start to descend and then ascend later.
How do hot air balloons descend?
They have to let out the hot air a little at a time.

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.
