Why do mylar balloons stay inflated longer than latex balloons?
Mylar balloons are less porous to helium than are latex balloons.
Why are small balloons cheaper than large balloons?
There's been less inflation.
Is inhaling more than 5 helium balloons bad for you?
It might make you light headed or possibly pass out, but it won't kill you.
Explain why helium-filled Mylar-foil balloons can float freely for several weeks but latex balloons for less than 24-hours?
Mylar-foil balloons are less porous to helium than latex balloons. Basically, it takes helium longer to seep through the Mylar-foil.
Why do helium balloons float better than just air balloons?
helium is less dense than air. :) so helium will float better than air
Why is air balloons filled with helium?
Because it is a safe gas that is less dense than air, thus balloons float in air
Why do mylar balloons hold helium longer than latex?
They are less porous
How do balloons rise?
Balloons rise when they are filled with something that is less dense than air, like helium. In other words, the gas in them is lighter than the rest of the air.
How is it possible that the volume of a helium tank is much less that 500 balloons it can fill?
The gas in the tank is under much greater pressure than in the balloons. In other words, the He atoms in the tank are much closer together than in the balloons.
Why do balloons float?
0they float because they are less dense than the air surrounding it
Why do you use helium in balloons?
Helium is less dense than air, and therefore the balloon will float.
What are some uses of helium?
Helium is used in balloons because it is less dense than air.
