1. liquid hydrogen
2. Liquid hydrogenLiquid hydrogen (LH2 or LH2) is the liquid state of the element hydrogen. Hydrogen is found naturally in the molecular H2 form. To exist as a liquid, H2 must be pressurized above and cooled below hydrogen's Critical point. However, for hydrogen to be in a full liquid state without boiling off, it needs to be cooled to 20.28 K (−423.17 °F/−252.87°C) while still pressurized.
