The lower the atmospheric pressure, the less helium is needed.
As long as the tank holds at least 113.1 cubic feet, 1 would be sufficient.
Balloons are filled with gas (such as helium), or a mixture of gasses (such as air) or hot gasses (such as hot air).Helium.
When helium is used to fill a balloon, it expands to fill the space inside the balloon due to its low density. The helium gas takes the shape of the balloon because it moves and distributes evenly throughout the balloon's interior.
To determine how much helium is needed to fill a 6-foot balloon, we first need to calculate its volume. A 6-foot balloon has a diameter of about 6 feet, giving it a radius of 3 feet. The volume of a sphere can be calculated using the formula ( V = \frac{4}{3} \pi r^3 ), which results in approximately 113.1 cubic feet. Therefore, it would take roughly 113.1 cubic feet of helium to fill the balloon completely.
A sphere with 3-ft diameter has about 0.4 cubic metre of volume.
You fill up the balloon by asking G for the super helium.
It typically takes about 0.5 pounds of helium to fill a 12-inch latex balloon.
Helium gas is lighter than air and hence balloons filled with helium will float in air.
Helium is a lighter element compared to air, helium also has fewer molecules than air.
Yes, a helium-filled balloon will float in the air because helium is less dense than the surrounding air. When filled with helium, the balloon experiences a buoyant force that causes it to rise and float.
I personally fill a balloon with my breath, the balloons I buy are already filled with helium.
Fill the balloon with a gas which is lighter than air: helium, for example.
