Answer:The balloon floats because it contains a gas that is lighter than air. Gas diffusion through the balloon skin causes a loss of buoyancy and eventually the balloon drops below neutral buoyancy in the air and sinks. It is difficult to contain the Helium in balloons for long because the atoms are very small.
