Will a balloon filled with He deflate faster than one filled with hydrogen?
http://answers.yahoo.com/question/index?...
And people answered that it was because He had smaller particles than nitrogen or oxygen. Smaller how? Are we talking atomic/molecular radii?
Well, He radius is 31 pm, hydrogen has a covalent radius of 36 pm (and two atoms to a molecule, unlike the monoatomic He), but I believe the hydrogen-filled balloon will deflate faster than the helium-filled one. Can you tell me why?
Answer:
He has less mass per unit volume compared to air and hence He balloon deflates faster compared to air balloon.
He balloon will deflate slower than H balloon. The reason is that the rate of mass of gas leaving the balloon depends on the pressure difference inside and outside the balloon which is the same in the case of both balloons. Now there is more mass of He in the balloon compared to Hydrogen as He is denser than hydrogen. So more mass takes longer time.
Size does matter...lol. I think you are right, because H2 is bigger than He. Also, He is a nobIe gas which may make it more "slick". Think of the shape of the H2 , though. Is it more narrow down its interatomic axis?? I originally thought H2 also.
a balloon filled with Hydrogen should deflate faster than one filled with helium.
