Why does a balloon fall instead of float?
you fill a balloon with air, tie it off, and release it, it will fall to the floor. Why does it fall instead of float? This is because the air is the same dense as the air on the outside, but the weight of the balloon it self causes it to fall. Helium is less dense than the air, so the balloon would float.

Why does helium float and air doesn t?
2 Answers. Helium balloons are pulled by gravity, as are all objects with mass. The reason a normal balloon doesn’t float is that the weight of the air it displaces is just a little bit less than the weight of the balloon (because it is filled with air, but the rubber of the balloon itself is more dense than the air).
Does helium have less mass than air?
Originally Answered: How much lighter is helium than normal air? 14.5 times lighter. Air has a mass of 29 grams per mole, which translates to 1.2754 kg/cubic meter at standard temperature and pressure. Helium has a mass of 2 grams per mole, which translates to 0.088 kg/cubic meter at STP.
What weighs more helium or oxygen?
Helium has a density of 0.0001785 per cubic centimeter, while oxygen is 0.001429 per cubic centimeter. Therefore, helium is lighter than oxygen and it will rise higher than the oxygen-filled balloon.
