It would depend on the amount of Helium within the truck.\n\nJust because Helium is lighter (less dense) than air does not mean that it does not have mass (and thus weight).\nFor a given volume of Helium and air at the same pressure, the Helium would have less mass.  However, if one pressurized the Helium and/or had enough moles of the gas, one could actually be increasing the overall weight of the car by adding the Helium.\nIn orer to lighten the car, the idea would be to displace the surrounding "fluid" (air) but at the same time, by adding as little additional mass as possibe.\n\nAny effects of Helium upon the overall weight of the vehicle will be totally negligible using any normal amount of Helium.  One would need a small blimp's worth of Helium to have any real effect.

It depends on where you live. Some flower shops also sell balloons and will inflate them,a balloon shop, sometimes a Hallmark store, some Wal-Marts have helium tanks. Just check the yellow pages of your local phone book. You should be able to find some place that will do this for you.

I guess the helium ballon will lift the same mass, not more. \nThis is because although the mass will weight less (1/6), also the ballon will have less lift force because this depends on the volume x density x g(moon), and g(moon) is 1/6 also, so the less weight counteracts with less lift force.

Space is not a perfect vacuum devoid of particles, atoms, or molecules, it is a partial vacuum.  It is just that the density of matter in space is so small that it doesn't apply pressure against the balloon. If the balloon pops, the air inside the balloon is dispersed at the molecular and atomic level since air is comprised mostly of molecules: O2, CO2, CH4

Boy, you probably need to consider the liquid containing bottle's dimensions too. \nThe total average height of liquid will be 0.8 m + half the height in the bottle (say.\n\nAssuming the average height of liquid in the bottle = 100 mm = 0.1 m,\ntotal average height = 0.8 + 0.1 = 0.9 m\n\npressure exerted = potential energy= densityx acceleration due to gravityx height\n\nLength of needle can be neglected because they are usually installed horizontally and hardly add to the height. Also, it can be presumed that the flexible tubing and the needle were fiiled with the liquid at the comencement of the I.V drip. and the pressure difference if any due to this may be neglected.\n\nKinetic energy imparted = potential energy\n\n1/2 m v^2 = mgh\nv^2 = 2 gh\nv^2 = 2 x 9.8 x 0,9\nv= (2 x 9.8 x 0,9)^1/2\nv = 4.2 m/s= 420 cm/sec\n\nvolume to be injected/time in seconds\n= 490/ (35x60) = 1.4 cm3/ sec\n\nvolume flow (V) = speed (S)x cross section area\narea = V/S= 1.4/420 = 1/300 cm^2 \narea = 1/2 pi r^2\n1/300 = 1/2 x 22/7 x r^2\n\nr^2 = 1/300 x 2 x 7/22 cm2\n      = 7/ 3300 cm2\n\n  r    = .046cm = 0.46 mm\ndiameter (d) = 2r= 2 x 0.46= 0.92 mm.................

if your balloon were super super to the highest level so so so so so so so so so so so so so so so very very very very very strong.... as in... that it would survive at like zero pressure, your helium filled balloon would reach the outer space...\notherwise, it would'nt even reach the middle of the atmosphere..

a tv program showed that approximately 2600 balloons filled with helium is needed to lift 20 kg child a few centimeters of the ground. (if i remember right, of course)

Depends on local airpressure and weight of the man.\nAt 1013 millibar (= 1 atm) the mass of 1m³ of air is 1.29 kg\nand the mass of 1 m³ of helium is 0.178 kg\n\nTo make a mass of 75 kg weightless you'll need 75/(1.29-0.178) = 67 m³ of helium, to lift it a little bit more.

Archimedes principle for buoyancy is:\nFb = (mass of the surrounding fluid)*(gravity)\nFb = buoyant force\nThe mass of the surrounding fluid is air and can then be calculated as:\nmass of surrounding fluid = (Density of Air)*(Volume of Balloon)\nThe buoyant force then can be written as\nFb = (Density of Air)*(Volume of Balloon)*(Gravity)\n\nThe opposing force to buoyancy is the gravity force and can be written for the helium balloon as:\nFg = (mass of helium + load of balloon)*(gravity)\nMass of Helium = (Density of Helium)*(Volume of Balloon)\nSo, then the equation looks like:\nFg = (Density of Helium)*(Volume of Balloon)*(gravity)\n+ (load of balloon)*(gravity)\n\nWhen a balloon is going up it has a larger buoyant force upward than the gravity force (Fg) downward.  When they are equal then the net force is zero and can be written as:\n\nFnet = Fb - Fg = 0\nor \nFb = Fg\nThe full equation then looks like:\n(Density of Air)*(Volume of Balloon)*(Gravity) = (Density of Helium)*(Volume of Balloon)*(gravity)\n+ (load of balloon)*(gravity)\n\nGravity cancels and the equation can then be algebraically arranged as: \n(Volume of Balloon) = (load of balloon)/(Density of Air - Density of Helium)\nor\nV= m / (Air density - Helium density)\n\nPlugging in the values that were stated in your problem we get:\n800kg/(1.29kg/m³ - 0.18kg/m³) = 721m³

Helium is a gas that is ONLY found trapped inside rocks ( on Earth ).\n\nThis is because Helium is so light that it will escaped into SPACE when released.  ( Helium is not found in the air )\n\nYour helium balloon will explode before it stops rising.\n\nIf the balloon doesnt explode ( for example only ) , then it will rise into space and stabilize in a orbit at an equilibrium point where the gravitational attraction of the Earth to the substance of the balloon matches the lift of the balloon ( the tendency of Helium to escape ).\n\nI dont know where this point would be but i dont think its necessary to understand your question.

nitrogen, probably helium and hydrogen too.

I've never tried this or heard of it being done, so ask your teacher if it's safe to try this experiment. Take a balloon that has a good long neck on it and force it into the tab opening of an empty aluminum soda can. Then blow the balloon up as hard as you can so that it expands to fill the inside of the can and forces all the air out of the empty can (which really wasn't empty because it had air in it!) Continue to pinch off the neck of the balloon with your fingers so the air won't come out of the balloon. Now fill up a big tall kitchen pot or the sink half way and turn the aluminum soda can upside down completely into the sink or pan of water until the top of the can and pinched off balloon are partially submerged under the water. Now start letting the air out of the balloon gradually and watch the bubbles come to the surface of the water. When all the air is out of the balloon, it still has atmospheric air pressure inside it which keeps the can from being crushed by the atmospheric air pressure of the air in the room above the water level. So try to pull the balloon out of the soda can gradually while making sure to keep the soda can tab and balloon openings under the water level. Results? Does the can get crushed by atmospheric air pressure? Of course, we always have about 14.7 pounds per square inch of atmospheric pressure at sea level. You may have to experiment with different container types that your teacher says are safe to experiment with and one that had the globular shape of a blown up balloon would allow the air to be pushed out fully. You should wear good safety glasses in case any other container (like thin plastic) rather than the aluminum container shatters in the process of imploding.\n \nPS,  Using a wider mouth container, like the aluminum soda can with it's top sawed off, you could pull the balloon out quickly even when it was blown up with air. Don't cut yourself on any sharp metal edges though. The metal or plastic container material can't be too strong and thick because it can't collapse easily then under the force of the atmospheric air pressure.

Lecture bottles are very small compressed gas cylinders, typically 2-3 inches in diameter and 12-18 inches in height. They are used to deliver small quantities of compressed gas, generally to science labs. I don't know where it got the name, but maybe the small size was used for science demonstrations during science class lectures?

Some novelty balloon are as large a 6 foot in diameter. But we will assume that you are dealing with a 1 foot diameter 300mm balloon. \n   Also the ambient temperature plays a role so we will assume you are about halfway between equator and north pole on an average summer day say 70 degrees Celsius.\n  Wind speed we will negate, as you will pick an absolutely calm day.\n  Thus you have two fundamental forces that of gravity on the balloon. And the lift caused by a difference of atomic weight of the helium vs air. \n  Then one must run tests to determine at what circumference the novelty balloon will burst, and the air pressure at various elevations.\n  We will assume the balloon can double in volume before exploding  and that air pressure goes down geometrically as the balloon rises (this is not true by the way) (some balloon will pop before others and air pressure vary's from day to day area by area etc.)\n Using all these estimated averages I predict that your balloon will reach a height of 5 kilometers before bursting.\n  However experience in the field has shown me that they usually rise so gradually that they first develop a slow leak and then float gently back to earth as they lose their helium.\n  There they are frequently eaten by some poor animal who dies as a result of your experiment so please do not do this at home Thanx

Helium and it is any latex material.
