Can anyone give me at least 7 fun facts about hydrogen?
Hydrogen is less flammable than gasoline. The self-ignition temperature of hydrogen is 550 degrees Celsius. Gasoline varies from 228-501 degrees Celsius, depending on the grade. When the Hindenburg burned, it took some time before the hydrogen bags were ignited. Hydrogen disperses quickly. Being the lightest element (fifteen times lighter than air), hydrogen rises and spreads out quickly in the atmosphere. So when a leak occurs, the hydrogen gas quickly becomes so sparse that it cannot burn. Even when ignited, hydrogen burns upward, and is quickly consumed, as shown in the Hindenburg picture. By contrast, materials such as gasoline and diesel vapors, as well as natural gas are heavier than air, and will not disperse, remaining a flammable threat for much longer. Hydrogen is non-toxic. Hydrogen is a non-toxic, naturally-occurring element in the atmosphere. By comparison, all petroleum fuels are asphyxiants, and are poisonous to humans. Hydrogen combustion produces only water. When pure
