Can a balloon filled with nitrogen float
WebSep 8, 2014 · For some applications, H 2 is more appropriate. For example, weather balloons often use hydrogen due to cost, with side benefits being lower density and lower diffusion rates across the membrane; flammability is not a major concern. Since helium is on shortage, fewer and fewer places use it any more for balloons.

Webfirst depend on the number of air molecules, N, in the balloon. As you add more and more air to something like a bicycle tire, the pressure increases. If there weren't any air molecules at all there wouldn't be any pressure. Pressure is directly proportional to N - an increase in N causes an increase in P. If N doubles, P also WebSep 16, 2024 · You breathe into a balloon, and nitrogen escapes from your lungs. Your own breathing air weighs more than helium, so it won’t cause balloons to float as high. You are aware that helium filling is required if you want the biggest air filled balloons. You might not know where to find it, though.
