There's been less inflation.
It might make you light headed or possibly pass out, but it won't kill you.
helium is less dense than air. :) so helium will float better than air
Because it is a safe gas that is less dense than air, thus balloons float in air
hellium is a gas that makes light objects float e.g. balloons
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.
Balloons can be filled with air (don't float), or with hydrogen or helium (float because the gas is less dense). Hot air balloons use burners to heat the air so that it becomes slightly less dense than the cooler air around it, providing some lift.
Helium is less dense than air, and therefore the balloon will float.
Helium is not only very light, it is also monatomic, it's particles are all made up of a single atom. Air molecules, oxygen, and nitrogen mainly are larger and hevier and diffuse through much more slowly.
Helium is used in balloons because it is much less dense than air, allowing the balloons to float and is completely nontoxic and nonflammable unlike hydrogen, which is otherwise a superior lifting gas.
The density of helium is less than that of air. Due to this reason, balloons filled with helium will float in air.
If a balloon is filled with a substance that's less dense than air ... such as helium, hydrogen, steam, or warmer air ... then the balloon is less dense than air.
