What else can I help you with?
When you heat the air inside a hot air balloon, it rises. Why does this occur?
D: The hot air inside the balloon becomes less dense than the air outside the balloon.
How does a air balloon fly?
air is heavier than balloon, air rises
Does an empty balloon weigh less than a balloon full of air?
Yes, an empty balloon weighs less than a balloon filled with air because the air adds to the overall weight of the balloon.
Is a helium balloon heavier than air filled balloon?
No. Helium is lighter than air
How does air make a balloon fly?
air is heavier than balloon, air rises
How does a helium balloon float but not a balloon filled with air?
Helium is a lighter element compared to air, helium also has fewer molecules than air.
How does a hot-air balloon rise?
The upthrust on the balloon is greater than the weight of the balloon. Thus, it rises upwards. The upthrust on the balloon is greater than the weight of the balloon because the air inside it has a lower density than the surrounding air.
Is a hot air balloon as dangerous as a car?
The dangers are somewhat different. You are very unlikely to have high speed collisions in a balloon, but if you fall out of a balloon, you have a lot farther to fall than if you fall out of a car. Either of these vehicles can be dangerous or fatal if they are not used correctly.
Why does an air balloon not float?
A hot air balloon floats because the air inside is heated, making it less dense than the cooler air outside. This creates a buoyant force that lifts the balloon. If the air inside the balloon is not heated, it will not be less dense than the surrounding air, and the balloon will not float.
Why was the airplane harder to invent that the hot air balloon?
Balloon is lighter than air.
Why the deflated balloon is lighter than a inflated balloon?
A deflated balloon is lighter than an inflated balloon because the air inside the inflated balloon adds weight to it. When the air is released, the balloon becomes lighter because it is no longer burdened by the added weight of the air molecules.
What gas put in a balloon would make it fall?
Any gas that is more dense than air.Answer:It is a bit more complex than that - an air filled balloon would still fall because air has the density of air. In a normal inflated balloon the air in the balloon is compressed and has a density more than uncompressed air. If the "balloon" were a plastic bag wiith no air pressure above the pressure of the surrounding air, the balloon would still fall as the combined (average) density of the balloon/bag system is greater than the surrounding air. Even if the balloon were filled with a gas with a lower specific gravity than air the balloon wll fall if the compressed gas density excedes that of the surrounding air or if the combined (average) density of the balloon/bag or balloon system is greater than the surrounding air.
