As the flame burns it heats the air around it making the air less dense than the cooler air above, the warm air particles rise to the top of the balloon and the balloon rises with the air. Essentially a hot air balloon uses a convection current to stay in the air.
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.
The piece of equipment that put the flame up into the balloon is called the 'burner' in most parts of the world. It is also sometimes called a 'heater'.
The burner in a hot air balloon is crucial because it generates the hot air that fills the balloon's envelope. By heating the air, the burner decreases its density, allowing the balloon to rise due to the principle of buoyancy, as hot air is lighter than the cooler air outside. The burner also allows for altitude control; by adjusting the flame, the pilot can maintain or change the balloon's height. Without the burner, the balloon would not be able to lift off or stay airborne.
To increase enthalpy.the burner uses flames to heat the air so the balloon will rise
The heat source of a hot air balloon is typically a propane burner. This burner ignites propane gas, producing a flame that heats the air inside the balloon's envelope. As the air inside the envelope becomes warmer than the cooler air outside, it creates buoyancy, allowing the balloon to rise. The pilot can control the altitude by adjusting the flame to change the temperature of the air inside the balloon.
Propane. This is what makes the flame that heats the air in the balloon.
yes there is a flame at the top of a Bunsen burner. there are three different types light blue blue and yellow
Yes, hot air balloons use a burner, which is a type of machine that blows hot air into the envelope of the balloon. The burner typically runs on propane and produces a flame that heats the air inside the balloon, causing it to rise. As the hot air inside the envelope becomes lighter than the cooler air outside, the balloon ascends. The pilot can control the altitude by adjusting the flame and thus the temperature of the air inside the balloon.
how do you make the flame on busen burner bigger
No, holding a balloon under a flame will cause it to pop because the heat weakens the rubber material, leading to a sudden burst. It's not advisable to expose a balloon to direct flame or heat sources.
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.
As a safety flame, keep it on this if the burner is not in use :)
