Does letting helium out of a balloon (without refilling the space) make it get heavier or lighter? 948 viewsJanuary 3, 2024 Question90.96K February 10, 2020 0 Comments Maybe I’m just too dense to figure this out…. In: Physics 9 Answers ActiveNewestOldest Anonymous Posted February 10, 2020 0 Comments It you let some helium out, it will get lighter because helium has mass. However, it will also become smaller, which will cause it to displace less air. It’s displacement of air with a lighter gas that allows the helium balloon to float.
