Hydrogen in a balloon
WebTo accomplish this the calculator adds the weight of the balloon, the weight of the payload, and the positive lift. It then divides this summation by 27.82 to get the amount of helium you need in cubic feet (1 cu.ft. helium can conservatively lift 27.82 grams). Next the Balloon Performance Calculator calculates the altitude at which the balloon ... Web14 jun. 2012 · Balloon Development Challenges for Mars. Ballooning in the Martian atmosphere is complicated by the fact that the Martian carbon dioxide atmosphere is very cold (200 K or -73 degrees C), and it is very thin at 0.006 bar, where 1 bar = 1 atmospheric surface pressure on Earth. In order to fly balloons at Mars, the balloons must be made …

A lot of heat and (hopefully)hydrogen was released. However, within 2-3 hours, the balloons started losing altitude and began falling down. I supposed it was caused by losing the gas slowly. Web25 nov. 2007 · Answer. In order to get a floating balloon you want a gas which is as light as possible. Helium is quite a lot lighter than air: it's about an eighth of the density of air. Hydrogen is about a sixteenth the density of air, so it'll float in air and will in fact float …
