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.

How do balloonists make the balloon descend gradually?
The balloonist would turn of their burner so that the balloon can lose its latitude and then gradually the balloon will come down.
What causes a balloon to fall to the ground?
It's very simple to see the answer. Balloons have a certain type of air pressure and because it is greater than the air around it, it climbs. However, when the air pressure in a balloon is less than the air pressure outside the balloon, the the balloon will start to descend.
Why doesn't a hot air balloon stay in the air forever?
Because the hot air gradually cools causing it to descend. To stay aloft the air needs to be re heated, to do this it needs fuel of some sort and there is a limit to the amount of fuel that can be carried. Balloons have been built that use solar heating to heat the air but they are rather difficult to control, and no one has yet solved the problem of what to do when there is no sun, especially at night!
Will a balloon pop in space?
That depends on how much air is in the balloon and how high the temperature gets. As the sun shines, it heats the air in the balloon. This causes the air to expand. This air pushes against the insides of the ballon making it swell up and stretch. If there is enough air in the balloon and the temperature increases to a high enough level, then the air pressure can get to high, it will cause the balloons skin to stretch to far and the balloon can pop.
What are some applications for Charles law?
Hot air balloons are an ingenious application of basic scientific principles. Here we will show exactly how the balloon works, what makes it rise and fall and how a pilot is able to maneuver it when it is in the air.The basis of how the balloon works is that warmer air rises in cooler air. This is because hot air is lighter than cool air as it has less mass per unit of volume. Mass can be defined by the measure of how much matter something contains. The actual balloon (called an envelope) has to be so large as it takes such a large amount of heated air to lift it off the ground. For example, to lift 1000 pounds worth of weight you would need almost 65,000 cubic feet of heated air! To help keep the balloon in the air and rising, hot air needs to be propelled upwards into the envelope using the burner (see separate section on burners for more information.)A hot air balloon is made up of 3 main parts:The EnvelopeThe actual fabric balloon which holds the airThe BurnerThe unit which propels the heat up inside the envelopeThe BasketWhere the passengers and pilot standThe burner uses propane gas to heat up the air in the envelope to move the balloon off the ground and into the air. The pilot must keep firing the burner at regular intervals throughout the flight to ensure that the balloon continues to be stable. Naturally, the hot air will not escape from the hole at the very bottom of the envelope as firstly, hot air rises and secondly, the buoyancy keeps it moving up.The controls for piloting a balloon are actually extremely simple....1 - To move the balloon upwards - the pilot opens up the propane valve which lets the propane flow to the burner which in turn fires the flame up into the envelope. Works in much the same way as a gas grill, the more you open the valve, the bigger the flame to heat the air, the faster the balloon rises.2 - To move the balloon downwards - the 'Parachute Valve' at the very top of the balloon is what is used to bring the balloon down towards the ground. It is essentially a circle of fabric cut out of the top of the envelope which is controlled by a long chord which runs down through the middle of the envelope to the basket. If the pilot wants to bring the balloon down he simply pulls on the chord which will open the valve, letting hot air escape, decreasing the inner air temperature. This cooling of air causes the balloon to slow its ascent.So essentially this takes care of the up and down movement, so how does the balloon move from place to place? Again the answer is very simple, the pilot can maneuver horizontally by changing the vertical position of the balloon because the wind blows in different directions at different altitudes. If the pilot wants to move in a particular direction they simply ascend and descend to the appropriate level and ride with the wind.BY: John Michael Manga-o19-
How do balloonists make the balloon descend gradually?

How does a balloonist control the fall and rise?
A balloonist controls the balloon's altitude by adjusting the temperature inside the envelope. By heating the air with burners, the balloon rises, and by allowing the air to cool, the balloon descends. Additionally, the balloonist can control horizontal movement by finding winds blowing in different directions at varying altitudes.
To descend either suddenly or gradually particularly to descend by the force of gravity.?
TO fall or fallen
Who was the the first person to make parachute descend in 1783?
Blanchard, French aeronaut (Balloonist) also invented the parachute as a safety device. The date looks okay.
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.
How do hot air balloons descend?
They have to let out the hot air a little at a time.
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 Would a hot air balloon pilot heat or cool the air in the balloon to make it rise?
Heating the air makes less air take up the same space, so the air inside the balloon is lighter than the surrounding air. The pilot turns off the burner to help the balloon to maintain the current altitude or to descend.
What causes a balloon to fall to the ground?
It's very simple to see the answer. Balloons have a certain type of air pressure and because it is greater than the air around it, it climbs. However, when the air pressure in a balloon is less than the air pressure outside the balloon, the the balloon will start to descend.
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.
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.
