WebHot air balloons fly because of the law of buoyancy, also called Archimedes’ principle. This principle states that an object partially or completely submerged in a fluid (liquid or gas) is acted upon by an upward force equal to the amount of fluid displaced by the object. WebAug 17, 2024 · This means that the balloon displaces a volume of 4000 m³ of cold atmospheric air. At an ambient temperature of about 24 °C, the air has a density of about 1.17 kg/m³. With a volume of 4000 m³, the balloon thus displaces a cold air mass of about 4700 kg. According to the Archimedes’ principle, this results in a buoyant force of 47 kN. WebApr 2, 2012 · Hot air is less dense than cool air; the heated air causes the balloon to rise simply because it is lighter than an equal volume of cold air. Buoyancy is an upward force that the air exerts, and it helps hot-air balloons and blimps stay in the air.
