This lifting force comes from helium weighing less than air, resulting in an effect known as displacement. Because the surrounding air has been displaced by a substance with less weight per unit of volume, it is pushed away (upward, thanks to gravity) by the heavier substance.

How much can a helium balloon lift?
depends how big the helium balloon is and how many
How many grams of helium must be added to a balloon containing 8g helium?
To inflate a balloon to a desired size, we need to know the volume and required lift. Typically a 9-inch helium-filled balloon can lift about 8g of weight. If you want to increase the lift, you can add more helium.
How do you make a balloon lift without helium?
There are actually a number of ways to make a balloon lift, without helium. Hydrogen is even less dense than helium (but has the disadvantage of also being highly flammable). And since hot air is less dense than cooler air, you can lift a balloon just by heating air. Since hot air is less expensive than either helium or hydrogen, that is a popular technique.
How does a helium balloon float but not a balloon filled with air?
Helium is a lighter element compared to air, helium also has fewer molecules than air.
How much helium is needed to lift 400 pounds?
To lift 400 pounds, you would need approximately 74.3 cubic feet of helium. Helium is lighter than air, so it provides lift when contained in a balloon.
What gases lift a balloon into the air?
Anything less dense than air (hydrogen, helium, hot air).
Why do helium balloons float down?
Helium balloons float down due to the weight of the balloon being greater than the lift force generated by the helium inside. As the helium inside the balloon slowly leaks out over time, the lift force decreases, causing the balloon to float down.
How many helium balloons can lift up a brick?
depends on how large the balloon is! ;D
How many helium balloons does it take to lift a 20 pound frozen turkey?
It would take approximately 480 helium balloons to lift a 20-pound frozen turkey. Helium can lift about 0.04 lbs per balloon, so 20 lbs divided by 0.04 lbs per balloon equals 500 balloons.
Can you lift a book with a balloon?
Yes, a balloon may be able to lift a book depending on the size and weight of the book in relation to the lifting capability of the balloon. The balloon would need to be large enough and filled with enough helium to counteract the weight of the book.
How do you make a balloon without a balloon?
There are actually a number of ways to make a balloon lift, without helium. Hydrogen is even less dense than helium (but has the disadvantage of also being highly flammable). And since hot air is less dense than cooler air, you can lift a balloon just by heating air. Since hot air is less expensive than either helium or hydrogen, that is a popular technique.
Can helium lift 72 pounds into the air?
Yes, if you have enough helium in a balloon that is large enough and strong enough to stand the strains involved.
