For you chemistry and physics types: does the lifting power of helium change according to how small of a space you put it in?

1 Answer

Answer :

answer:Yes. Basically the buoyancy of an object will depend on its volume and density. Lift has to do with displacement of air and density of the gas displacing the air. In a rigid balloon you could get a lower density for the displaced air than a non-rigid balloon using the same mass of gas inside. This is due to atmospheric pressure on the non-rigid balloon preventing very low densities from occurring within the balloon.
