How do helium balloons work?

Answer 1

helium balloons get filled with a amount of air in which is called helium it is used to make balloons float around in air. helium is a inert,gaseous element!!!!!

yea i kenisha am smart
Helium is less dense than air, therefore a helium-filled balloon will float in air.
Helium is lighter that air, so it effectively floats on air. As a helium balloon is submerged in air, it rises upwards (like an air filled bubble in water).

Answer 2

I dont fully understand the question, but helium is alot lighter than air, and the elastic that makes up the balloon is very light. So helium in air is like air in water, the helium in the balloon forces itself up as high as it will go.

Answer 3

Helium molecules are less dense then air molecules causing the helium in a balloon to rise. Sorry, just noticed you said hot air balloons in which case I have no idea but I would assume there is no helium in a hot air balloon as it uses hot air to float in the sky

Answer 4

Helium is a lighter-than-air gas that is used to fill balloons. When helium is pumped into a balloon, it causes the balloon to become buoyant and float in the air due to the difference in density between the helium gas inside the balloon and the surrounding air. This is why helium balloons rise up instead of falling down.
