Why does helium balloon float in air 9th standard Note ​

Answer»

Answer:

The buoyancy force STILL just depends on the density of the air and the volume of the OBJECT. So, why does a helium balloon float? The only thing SPECIAL about a helium GAS is that it has a significantly lower density than air (with a density of 0.179 kg/m3 for helium and 1.2 kg/m3 for air)
