The gaseous state of water is lighter than air (density 0.804 g/L at STP, average molecular mass 18.015 g/mol) due to water's low molar mass when compared with typical atmospheric gases such as nitrogen gas (N2). It is non-flammable and much cheaper than helium. The concept of using steam for lifting is therefore already 200 years old. The biggest challenge has always been to make a material that can resist it. In 2003, a university team in Berlin, Germany, has successfull… WebCan Helium Balloons Lift a Person?

How many grams of helium are required to lift an object weighing
Web9 jul. 2016 · 1,717. 806. The difference in density between air and He is about 1.08 kg/m 3 so you can lift about 1kg per m 3 of He. To lift a man of 80 kg you need more than 74 m 3 of He plus some to lift the container. If you compress the He to, say, twice the density, then the difference in density is now 0.91 kg/m 3, so you now need at least 88 m 3. WebThere is something incredibly neat about helium balloons!
