User: Which property of a filled balloon would be unchanged on the moon where there's no air and less gravity? A. mass B. weight C. volume D. density

Weegy: BEST ANSWER: A. mass ... the mass remains unchanged, but weight is something else. On earth, helium balloons don?t weigh anything because the atmosphere supports them. [ If you tried to put a helium-filled balloon on a scale, no weight would register because the buoyancy of the balloon is greater than the pull of gravity. But on the moon, the moon?s gravity would definitely pull it against a scale. Therefore, on the moon the balloon will actually register some weight, even with the moon?s gravity one-sixth that of earth. ]
