How much air volume does it take to lift 1 pound of weight from the bottom of a pond?
With a quick on-line search, I found that at 60° F, water weighs 8.338 pounds
per gallon. That's 15.35 fluid ounces per pound. (rounded)
To the level of precision that I'm working at right now, we can assume the density
of air to be zero, at least by comparison with the water, so that's your answer:
15.35 fluid ounces, or in round numbers, let's just say: 1 pint of air to lift 1 pound.

If a cube whose volume is 8000 cm3 and a mass of 16000 kg is under water what is the weight of the cube?
Archimedes' principle: an object in water experiences an upward lift equal to the weight of the volume of water being displaced. volume of water displaced = 8000 cm3 weight of water displaced ~ 1 g/cm3 at room temperature and sea level weight of cube in air = 16000 kgf lift ~ 8000 gf = 8 kgf weight of cube in water = 16000 kgf - 8 kgf = 15992 kgf
What is volume weight and density?
volume is how much space is in an object (an object with more volume would be bigger) weight is how heavy an object feels due to gravity (an object with more weight would be harder to lift) density is how much matter is in an amount of space (an object with more density would weigh as much as an object with less density but in a smaller space/volume)
What is the difference between 20 volume and 40 volume hair developer?
20 Volume (or 6%) developer will lift hair 2 levels and 40 Volume (or 12%) will lift hair 4 levels.
Does 40 volume versas 20 volume make hair lighter?
40 volume developer is used for high lift shades and will lift hair 4 levels. 20 volume developer is also used for lifting but will only lift 2 levels. 20 volume is used as well when going darker or for gray coverage as it lifts and deposits at the same time.
What happens when weight is greater than lift?
When weight exceeds lift, an object will descend or fall due to the force of gravity overpowering the upward force created by lift. This typically occurs in aircraft during a stall or when they are unable to generate sufficient lift to maintain altitude. The imbalance between these two forces leads to a decrease in altitude until the forces are equalized or the object reaches the ground.
Why is there a 45 pound weight in a gym?
Instead of adding a 25 pound weight, and then 2 ten pound weights, it would be much easier to add a 45 pound weight. A 45 pound weight is standard in every gym, and not everyone can lift 10 more pounds if there was a fifty pound weight (five extra pounds on each side totals to 10 more pounds to lift).
How many balloons does it takes to lift 1 pound?
it took 53 12" helium balloons to lift a pound, you have to add the weight of the string and balloons
How many pounds of weight could a preson lift with all 600 muscles?
one pound
How much should a 120 pound 20 year old lift?
There is no set amount that a person should be able to lift based on their body weight.
Can you lift a one pound weight with a ping pong ball?
Depends how hard the ping pong ball is.
What was the total weight of the Hindenburg?
I work it out to be 130.1 tones. I worked this out thus:- Hindenburg carried a gas volume of 7,062,000 cubic feet of Hydrogen. This volume of hydrogen, would produce 242.2 tons of gross lift and as Hindenburg's useful lift (the lift left after you subtract the weight of the structure from the gross lift) is documented at 112.1 tons. Thus 242.2-112.1 = 130.1 tones (the weight of the craft).
What is the average weight a 14 yr old 130 pound 5ft4 boy lift?
83-87 lbs
Does weight on model rockets matter?
Yes it does. The more weight that there is in the rocket, the more energy it takes to lift off. Its the same as if you raised your hand above your head and it's empty. Put a ten pound weight in it and you have to exert more energy to lift it.
How many pounds of force does it take to lift a 100 pound man out of corn up to his waist?
If you have a man submerged up to his neck in corn and you want to know how many pounds of force it will take to lift him out, information about the volume, weight, mass, density would be needed in order to calculate the force needed.
What are some exercises you can do with your 5 year old boy for weight loss?
Let the 5 year old lift 100 pound weights and he will lose tons of weight
Why will the same volume of hydrogen lift more weight than the same volume of helium?
Because He is two times 'heavier' (more dense) than H2
How what force is required to lift the 100 pound weight?
To lift a 100 pound weight, you would need to apply a force that is equal to or greater than 100 pounds. This is due to Newton's third law of motion, which states that for every action, there is an equal and opposite reaction. So, the force applied must be at least 100 pounds to overcome the force of gravity acting on the weight.
