Solution
A filled helium balloon rises because of the simple fact that helium is lighter than air.
As altitude increases, the density of the atmosphere decreases. So as a latex helium balloon rises, the outside air pressure diminishes, while the pressure from inside of the balloon remains the same. This causes the elastic material of the latex helium balloon to expand.
As the latex expands, the helium balloon increases in volume, thereby increasing its buoyancy. The more a balloon’s material can safely expand, the higher it will rise.
