Because they can
Yes
Helium gas is commonly used to make balloons float because it is lighter than air and creates lift. The helium gas in the balloon is less dense than the surrounding air, causing the balloon to rise.
Helium is less dense than air, and therefore the balloon will float.
a balloon, a tires, as you said, we actually use air to breath too.
A hot air balloon uses buoyancy to stay in the air. The air inside the balloon is heated, making it less dense than the surrounding air, causing the balloon to float.
Yes, it will It's actually better to use nitrogen in balloons because it floats better than helium.
I am fairly sure that hot air balloons use normal air. They rely more on the idea of bouyancy rather than using specal gases, such as helium. The hot air inside of the balloon is more bouyant than the cold air outside of the balloon. So that makes the balloon ascend till the temperature of the air inside of the balloon is equal to the temperature of the air outside of the balloon. Then as the air inside the balloon gets colder, the balloon starts to descend.

Helium gas is lighter than air and hence balloons filled with helium will float in air.
A balloon does not float with your breath because the air you blow into it is denser than the surrounding air. To make a balloon float, you need to use a lighter gas, such as helium, which is less dense than the surrounding air and creates enough lift to keep the balloon suspended.
Yes, a hot air balloon relies on Archimedes' principle to generate lift. The heated air inside the balloon is less dense than the surrounding cooler air, causing the balloon to float upwards as it displaces a greater volume of air.
No, but you can build a snowman. Yes, you can inflate a balloon in a bottle, although it is more difficult than inflating a balloon that is not in a bottle. The only problem that this presents is that it is possible for the balloon to block the opening of the bottle so that air will be trapped between the balloon and the bottle, which would prevent the inflation of the balloon. However, if you use a drinking straw you can create an avenue for air to escape.
