With a quick on-line search, I found that at 60Â° 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.

Q: How much air volume does it take to lift 1 pound of weight from the bottom of a pond?

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

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)

20 Volume (or 6%) developer will lift hair 2 levels and 40 Volume (or 12%) will lift hair 4 levels.

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.

On earth, any vertical force greater than 661.39 pounds will lift a mass of 300 kg.

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).

it took 53 12" helium balloons to lift a pound, you have to add the weight of the string and balloons

one pound

There is no set amount that a person should be able to lift based on their body weight.

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).

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.

83-87 lbs

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.
