to lift 1 kg or 2 pounds you need 0.16 kg of helium so for 2000 pounds you need 160 kg of helium or 320 pounds at 1 atmosphere
The weight of standard air is 1.2256 Kg/ Cubic Meter The weight of hydrogen is 0.0857 Kg/ Cubic Meter The weight of helium is 0.1691 Kg/ Cubic Meter Subtracting the weight of hydrogen from air gives you the gross buoyant lift of hydrogen as 1.1399 Kg/Cubic Meter Subtracting the weight of helium from air gives you the gross buoyant lift of helium as 1.0565 Kg/Cubic Meter These values are variable under altitude, pressure, temperature, humidity and purity of gas. Hope this helps you.
Mine was 200
Measure how much it can lift.
The answer would depend on the units used for the force. Since these are not specified, it is not possible to answer the question.
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)
depends how big the helium balloon is and how many
Approximately 15 cubic feet of Helium.
depends what theaverage is (sorry i couldn't answer properly )
1791.044776119403 cubic feet176 / 0.067 = 1791.044776119403
2000lbs check your answer
"Lift" is pretty much defined as the difference in weight of equal volumes of the lifting gas (helium or hot air) and the ambient air. As a comparison, a typical density of air is about 0.00018 g/cm3. At the same temperature and pressure, air would be about 0.00128 g/cm3. The difference is 0.00128 - 0.00018 = 0.0011 g/cm3. So 1 cm3 of helium can lift about 0.0011 g. Scaling that up, 1 m3 of helium could lift about 1.1 kg. To achieve equal buoyancy, the air would have to be heated to about 1850 Â°C. Normal operating temperatures for hot air balloons are closer to 120 Â°C. At this temperature, the air density is about 0.00090 g/cm3, so the lift would be about 0.00128-0.0090 = 0.00038 g/cm3 so by comparison, helium would be 0.0011/0.00038 = 2.9 times the lift of hot air.
Depends on the weight. Check the MythBusters website, they did an experiment on this.
helium molecules are much smaller than the molecules of wood pulp that make up the structure of paper. Thus helium gas will quickly dissipate through the paper itself, and into the environment without producing the necessary "lift".
2,000lbs = 907 (907.1847) kg
It's 2000lbs. that equals a ton.
It won't - at some time the balloon would burst or become the same density as the atmosphere, so stop rising. The above answer is correct. At about 110,000 feet or ~ 21+ miles (when the shuttle was well into the stratosphere) the balloon will burst. However to get the space shuttle into the stratosphere it would take 2,029,203,000 liters of helium and would cost approximately $ 146,102,616. Assumptions: Space shuttle weighs: 2,029,203 KG 1 Liter of helium can lift ~ 1 gram. Helium costs approximately 7.2 cents per gram. According to the NASA website it costs $450,000,000 to launch a shuttle. Maybe they should look into using helium to get them the first 20 miles.
