Under the same conditions, air has a density of 1.293 kg/m3. This means that at sea level on a 0ºC day, hydrogen provides enough buoyancy to lift 1.2031 kg per cubic meter, while helium can only lift 1.1145 kg per cubic meter of gas.
WebHydrogen -- a light and extremely powerful rocket propellant -- has the lowest molecular weight of any known substance and burns with extreme intensity (5,500°F). In combination with an oxidizer such as liquid oxygen, … WebSo to lift a person, say, 72 KG, you'd need a bit over 12 KG of helium, but that's a lot of helium. And, it may seem strange that 10 KG can lift 60 KG, but it's like holding a balloon under water. A balloon - which weighs very little in the air has significant lift in water because it's much lighter than the water surrounding it.
