Hot air has density less than the air surrounding the balloon. When the average density of the balloon filled with hot air is less than the density of the air outside upthrust is more than the weight of the balloon. therefore it keeps on rising up till the upthrust becomes equal to the weight of the balloon.
In a "hot air" balloon, which you refer to in your question, the gas is hot air. Heated air rises, so the balloon rises. The gas used in the burner, to heat the air, is propane.
Hot air balloons are filled with heated air, usually generated by a gas burner that heats up the air inside the balloon envelope. This hot air makes the balloon buoyant and allows it to rise in the sky.
Hot air is used in hot air balloons because when the air inside the balloon is heated, it becomes less dense than the surrounding cool air, causing the balloon to rise. This buoyancy principle allows the balloon to ascend and float in the sky. Using cool air would not provide the necessary lift for the balloon to fly.
You will find both in the sky.
A hot air balloon rises into the sky because the air inside the balloon is heated, causing it to expand and become less dense than the cooler air outside. This difference in density creates buoyancy, allowing the balloon to float upward. According to Archimedes' principle, the upward force exerted on the balloon by the surrounding air is greater than the weight of the balloon, enabling it to ascend.
Hot-air balloons can rise up into the air because hot air is lighter, allowing it to float up into the sky.

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.
Hot air rises because it occupies a greater volume per unit mass of air than cooler air, this makes it less dense. A hot air balloons fire generates hot air which floats inside the balloon, causing it to rise.

Because the peacefulness of drifting through the sky is unbelievable!!
A hot air balloon rises in the sky because the air inside the balloon is heated, making it less dense than the surrounding air. This causes the balloon to float upwards, as the less dense hot air inside the balloon is lifted by the denser, cooler air outside.
Hot air balloons like those from "King Tut Balloons" rise because hot air is lighter than cool air. A burner heats the air inside the balloon, making it less dense than the cooler air outside. This causes the balloon to lift gently into the sky, offering a magical flight over stunning landscapes like Luxor’s temples and pyramids.

The perpose of the Hot air Balloon is to lift objects of of the ground or to give people a very nice scenic veiw.get you highit was used for short travel and a good view in the sky.
