No, hot air balloons are kept up in the air by buoyancy, the same thing that keeps helium balloons up in the air, or that keeps ships afloat. The hot air in the balloon is less dense than the surrounding air, so the balloon weighs less than the air it displaces, at least while the balloon is rising.

What are three working forces on the hot air balloon?
Three working forces on a hot air balloon are lift (created by hot air inside the balloon being lighter than the surrounding air), gravity (pulling the balloon downward), and drag (resistance caused by the air as the balloon moves through it).
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.
Why does a balloon fall off a wall quicker on a hot humid day?
On a hot humid day, the air is less dense, which means there is less air resistance acting on the balloon as it falls off the wall. This decreased air resistance allows the balloon to fall more quickly compared to a cooler, less humid day.
What are the 4 forces involved in making a hot air balloon move?
The four forces are lift, weight (or gravity), thrust, and drag. Lift is generated by the hot air inside the balloon being less dense than the cooler air outside. Weight is the force of gravity pulling the balloon down. Thrust is provided by the burner heating the air inside the balloon. Drag is the resistance caused by the air pushing against the balloon as it moves.
What are the forces of a hot air balloon?
The forces acting on a hot air balloon are lift, weight, thrust (provided by wind), and drag. Lift is generated by the heated air inside the balloon being lighter than the surrounding air, causing the balloon to rise. Weight is the force of gravity pulling the balloon downward. Thrust is the horizontal force provided by wind to move the balloon in a certain direction, and drag is the resistance the balloon encounters as it moves through the air.

What are the advantage of a hot air balloon?
the mechanical advantage of a hot air balloon is this that we can use it in many good ways like it is for individual flight for every one, and can be use at any time but it depends on the air resistance + gravity because if the gravity is low the hot air balloon would fly far and far in the air and if the gravity is hifgh it would unable to fly and in air resistance if the air is high it would be difficult for a hot air balloon to fly and if air resistance is low it would be difficult for hot air balloon to fly in the air
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.
How do you keep an hot air balloon in the air indefinitely?
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.
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.
Why does a balloon fall off a wall quicker on a hot humid day?
On a hot humid day, the air is less dense, which means there is less air resistance acting on the balloon as it falls off the wall. This decreased air resistance allows the balloon to fall more quickly compared to a cooler, less humid day.
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.
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 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.
