a hot air balloon floats because of convection which means that the heat that is from the flame goes up than back down than replaces it with cooler air it goes in a cycle.
A hot air balloon floats in the air because it is buoyant due to the hot air inside the balloon being lighter than the cooler air outside. It is not propelled by engines or wings like an airplane, so it is more accurate to say it floats rather than flies.
A hot air balloon floats in the air because the air inside the balloon is heated, becoming less dense than the surrounding air. This creates a buoyant force that lifts the balloon. As long as the air inside the balloon remains hotter than the surrounding air, the balloon will continue to float.
As to the reason a hot air balloon floats has already been explained, I will answer your question regarding the flame. The gas burner provides the flame which is placed just in the mouth of the ballon, when lit it provides more heat to the cooling air in the balloon causing the balloon to maintain altitude.
A hot air balloon goes up because the air inside the balloon is heated, which makes it less dense than the surrounding cooler air. This creates a buoyant force that causes the balloon to rise. The pilot controls the altitude by adjusting the temperature of the air inside the balloon.
The longest someone has flown in the air is 50 hours!
The hot air is less dense than the air surrounding the balloon, so it floats in the surrounding air.
A hot air balloon floats in the air because it is buoyant due to the hot air inside the balloon being lighter than the cooler air outside. It is not propelled by engines or wings like an airplane, so it is more accurate to say it floats rather than flies.
The ideal gas law helps to explain why a hot-air balloon floats in the air. As the air inside the balloon is heated, it expands and becomes less dense than the surrounding air. This creates a buoyant force that allows the balloon to float.
Hot air makes a hot air balloon rise because hot air is less dense than the cooler air around it, so the hot air balloon floats on the cooler air around it.
Hot air balloon.
A hot air balloon rises and floats in the air because the air inside the balloon is heated, making it less dense than the surrounding cooler air. This difference in density creates lift, allowing the balloon to ascend.

Raising the air temperature inside the envelope makes it lighter than the surrounding (ambient) air. The balloon floats because of the buoyant force exerted on it. This force is the same force that acts on objects when they are in water
hot air baloons are able to fly because the hot air that is released in to the ballon wants to get out so there for it keeps pushing and that is how a hot air balloon floats
Hot air is less dense than cold air so it floats upwards. If you encapsulate this hot air with a bag and the lift produced exceeds the mass of the bag, the bag or balloon will be carried up with the hot air too.
