WebWhether they crashed into trees or experienced an engine fire, hydrogen was not the wisest decision. As we learned from the Hindenburg disaster, hydrogen is highly flammable, whereas helium is not. The fabric surrounding the body of the airships was incompatible with the risks of a flammable gas, which before was assumed to be safe. WebUsing the molar volume, the mass of 1 liter of helium (at 1 atmospheres of pressure) is found to be 0.178 g. If helium is used instead of vacuum, the lifting power of every liter is reduced by 0.178 g, so the effective lift is …
