Helium Balloon Falls in a Vacuum UCSC Physics

Foil Balloon with Helium Archimedes' Principle states that an upward force, or a force that opposes gravity, acts on an object that is immersed, either partially or fully, in a fluid. This force is known as a buoyancy force, and it is equal to the weight of the fluid that is displaced by the object, .

Inflating a Weather Balloon High Altitude Science

It attaches directly to your helium gas cylinder valve and reduces the pressure to less than 200 PSI. This ensures that the maximum pressure inside your inflation hose never exceeds 200 PSI. If you were to inflate your balloon without a gas regulator and accidentally stepped on the hose or twisted a kink into the hose, the unregulated pressure would cause the hose to explode.

9. Note According to the numbers above, each helium tank should give us about 2.3 balloons. To inflate a balloon from a tank with less than 1150 psi of helium, simply note the initial tank pressure and express all the helium into the balloon. Note the final pressure and calculate the ∆P of helium that was expressed into the balloon.
