As you heat air, or any other gas, it becomes less dense. Just like a bubble rising in an aquarium, the hot air will float above the denser, colder air around it. Get the air in the balloon hot enough, and it can lift the balloon canvas, the basket, and everyone inside it as … WebJun 20, 2024 · Hot air goes up, according to science, and because the air within the balloon heats up it makes the balloon hotter. The hot air balloon flight then rises upwards. The hot air within the balloon expands and gives it lift. The difference in temperature between the air within the balloon and the air outside determines the amount of lift. small alligator forceps

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. WebThis equation shows that as you heat the air in the balloon T 2 >T 1 (i.e. T 2 /T 1 >1) you get a positive force (F>0) which means that the force is up and the balloon rises. In summary, …
