To keep a Hot air balloon in the sky indefinitely you must keep all the air sealed and warm. The Hot air's lower density will keep it above the more dense, colder air. To demonstrate this put air inside a bottle and place it on-top of water. Notice how it stays "afloat".
========================================================
To keep a hot air balloon aloft indefinitely, the temperature of the air inside the balloon must be hot enough so that the difference in weight of the air inside the balance and an equivaletnt volume outside of the balloon equals or exceeds the total weight of the balloon and passengers. It doesn have to be air tight. Hot air balloons are open on the bottom. But it has to be air tight enough that the burner will be capable of keeping the air hot enough to maintain altitude.
It is not possible to keep a hot air balloon in the air indefinitely as the hot air in the balloon eventually cools down making the balloon descend. To maintain elevation, the balloon would need a continuous source of heat, which is not feasible for an extended period of time.

How do hot air balloonists keep their balloons going?
Hot air balloonists keep their balloons going by constantly monitoring and adjusting the temperature of the air inside the balloon. By heating the air using a burner, the balloon can ascend, and by allowing the air to cool, the balloon can descend. By managing this process, the balloonist can control the altitude and direction of the balloon.
Why does hot air balloon need fire so that it can fly?
A hot air balloon needs fire to heat the air inside the balloon. Heating the air makes it less dense than the surrounding air, causing the balloon to become buoyant and rise. The fire is used to maintain the temperature of the air inside the balloon to keep it flying.
How do hot air balloons trap air inside?
Hot air balloons work by heating the air inside the balloon envelope using a propane burner. When the air inside the balloon is heated, it becomes lighter and less dense than the surrounding air, causing the balloon to rise. The envelope of the balloon is sealed, which allows the hot air to be trapped inside and keep the balloon aloft.
Why must hot air balloon pilots do occasional blasts on the burner?
Hot air balloon pilots do occasional blasts on the burner to maintain the desired altitude. By releasing short bursts of hot air, pilots can control the temperature inside the balloon and regulate its altitude to ensure a safe and stable flight.
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.
Why aren't hot-air balloon flights scheduled on hot days?
Because the hot air balloon will keep on going up because the hotter the air gets the higher the hot air balloon will go!
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.
What force does a hot air balloon use to keep itself in the air?
A hot air balloon uses buoyancy to stay in the air. The air inside the balloon is heated, making it less dense than the surrounding air, causing the balloon to float.

By managing this process, the balloonist can control the altitude and direction of the balloon.
Does air resistance keep a hot air balloon in the air?
Yes, air resistance helps keep a hot air balloon in the air. When the balloon is heated, the air inside becomes less dense and lighter than the surrounding air, causing it to rise. The balloon is then carried by the wind, with air resistance helping to support its upward motion.
Why does hot air balloon need fire so that it can fly?
A hot air balloon needs fire to heat the air inside the balloon. Heating the air makes it less dense than the surrounding air, causing the balloon to become buoyant and rise. The fire is used to maintain the temperature of the air inside the balloon to keep it flying.
What happens when you put hot air into the balloon?
In hot air, particles are moving faster due to the increase in heat. This makes hot air lighter than cold air so the hot air will rise. When you put hot air into a balloon, the hot air will try and rise to the top. This allows the balloon to float in the air. Eventually the air will cool and sink back down which is why it's important to continuously pump hot air into the balloon to keep it up. Hope this helps! :)

How is a hot balloon lifted into the air?
to make a hot air balloon rise you use hot air
Why does a hot balloon fly?
A hot air balloon flies because it is filled with hot air. Hot air rises and causes the balloon to lift from the ground.
