Gaseous life forms
WebContact Us. Hydrogen can be stored either as a gas or as a liquid. Hydrogen gas storage typically requires the use of high pressure tanks (350-700 bar or 5000-10,000 psi), while liquid hydrogen storage requires cryogenic temperatures to prevent it boiling back into a gas (which occurs at −252.8°C). Hydrogen can also be stored on the surface ... WebNitrogen is a key component of the bodies of living organisms. Nitrogen atoms are found in all proteins and \text {DNA} DNA .
