By heating the air inside the balloon with the burner, it becomes lighter than the cooler air on the outside. This causes the balloon to float upwards, as if it were in water. WebMay 30, 2024 · When the balloon inflates, its volume increases. And it is this increased volume that causes the buoyancy. More volume -> more air displaced -> more buoyancy. If you could get a balloon to stay inflated without anything inside it, it would rise even faster than a balloon of the same volume with helium in it.
WebJun 20, 2024 · The hot air that fills the envelope of the hot air balloon is lighter than the air outside the envelope, which means the envelope will rise because its buoyancy is greater than the downward force of gravity. The downward force of gravity on a hot air balloon is constant and won’t change. WebHot air rises. The balloon envelope traps a large amount of air. If the air in the envelope is heated by a burner, the balloon will rise. If the air in the envelope is allowed to cool, or to escape, the balloon will de-scend.
