How Does A Hot Air Balloon Work?
1 episode - English - Latest episode: almost 3 years ago -Hot air balloons work thanks to the difference in density of the air inside the balloon with respect to the air outside.
Inside the balloon there is usually helium or hot air, both of which are less dense than the outside air.
The height that hot air balloons reach will depend on the density of the air inside the balloon, since once this is leveled with the outer density, the balloon will stop rising.
To descend, the density of the air in the balloon must be greater than that of the air outside. This handling of densities is the task of the balloon pilot...

How Do Hot Air Balloons Go Up?
July 09, 2021 06:59 - 7 minutes - 7.02 MBHot air balloons float in the sky for the same reason that ships float in the sea. A ship floats because it is supported by the water below it: the weight of the ship (pulling down) is exactly offset by the pressure of the water below it (pushing up). A ship does not float perfectly on the surface of the water, but partially sinks in the water depending on its weight. The larger the boat, the greater the area of water under it, the greater the force of the water pressure pushing it upward...
