Why does a helium balloon go up?
A helium balloon floats because helium gas is lighter than air. By filling a balloon with helium, the balloon also becomes lighter than air. The helium balloon floats for the same reason that objects float on water: objects less dense than water are pushed up by buoyant forces equal to the weight of water displaced by that object. What happens in water also happens in air, and the helium balloon is pushed upwards by a force equal to the weight of air it displaces.
