To put it simply, hot air balloons rise due to heat produced by the burning of propane, the heat travels up through the balloon's valve into the balloon itself (the envelope) and up to the parachute valve. Since heat rises, the hot air balloon its self rises.
Better answer: a boat floats on water because it weighs less than the water it replaces. likewise, a hot air balloon floats, because the weight of the total balloon + hot air is less then the volume of cold air it replaces. Air has a weight too, but normally you don't notice.

Why do balloons float in the air?
Balloons float in the air because they are filled with a gas that is lighter than the surrounding air, such as helium or hot air. This creates a buoyant force that allows the balloon to rise and float.
What is added to balloons and hot air balloons?
Balloons can be filled with air (don't float), or with hydrogen or helium (float because the gas is less dense). Hot air balloons use burners to heat the air so that it becomes slightly less dense than the cooler air around it, providing some lift.
Does a hot air balloon have helium inside it?
Hot air balloons do not use helium; they are typically filled with hot air. Helium is non-flammable and more commonly used in other types of balloons like weather balloons or party balloons. The hot air inside a hot air balloon is what allows it to rise and float.
Which principle explains why hot air balloons float in air?
Hot air balloons float in air due to the principle of buoyancy. When the air inside the balloon is heated, it becomes less dense than the surrounding cooler air, causing the balloon to rise. This is because the less dense hot air creates an upward force that is greater than the force of gravity acting on the balloon, allowing it to float.
Which force allows hot air balloons to fly?
Hot air balloons fly due to the principle of buoyancy. As the air inside the balloon heats up, it becomes less dense than the surrounding cooler air. This difference in density creates a lifting force that allows the balloon to float in the air.
Where in the atmosphere do hot air balloons float?
Hot air balloons float because hot air displaces cool air in the atmosphere
Why can hot air balloons float?
which gas is in ballons
Why do hot air balloons float up?

How air balloons float?
They are filled with hot air. The hot air raises and take the balloon with it
Why do you think hot-air balloons can rise into the air?
Hot-air balloons can rise up into the air because hot air is lighter, allowing it to float up into the sky.
How does warm air balloons float?
"Warm air", otherwise known as Hot Air Balloons, float because of one basic Law of Thermodynamics; heat rises. The air in a hot air balloon is hot, therefore, the balloon rises.
Why do balloons float in the air?
Balloons float in the air because they are filled with a gas that is lighter than the surrounding air, such as helium or hot air. This creates a buoyant force that allows the balloon to rise and float.

Do hot air balloons fly or glide?
neither..... they float with the wind! :-)
Does a hot air balloon have helium inside it?
Hot air balloons do not use helium; they are typically filled with hot air. Helium is non-flammable and more commonly used in other types of balloons like weather balloons or party balloons. The hot air inside a hot air balloon is what allows it to rise and float.
Why do balloons float up into the air?
At a hot air balloon festival, hot air balloons slowly fill and then rise majestically in the predawn sky. These hot air balloons fly because of two fundamental principles of physics: the ideal gas law and Archimedes's principle.
Which principle explains why hot air balloons float in air?
Hot air balloons float in air due to the principle of buoyancy. When the air inside the balloon is heated, it becomes less dense than the surrounding cooler air, causing the balloon to rise. This is because the less dense hot air creates an upward force that is greater than the force of gravity acting on the balloon, allowing it to float.
