Solid hydrogen is the solid state of the element hydrogen, achieved by decreasing the temperature below hydrogen's melting point of 14.01 K (−259.14 °C; −434.45 °F).
20 Αυγ 2020 · At low temperatures (below \(0^\text{o} \text{C}\)), it is a solid. When at "normal" temperatures (between \(0^\text{o} \text{C}\) and \(100^\text{o} \text{C}\)), it is a liquid. While at temperatures above \(100^\text{o} \text{C}\), water is a gas (steam).
1 Ιαν 2015 · Introduction. Hydrogen, the first element on the periodic table with an atomic number of 1, is truly in a class by itself. It does not belong to any family of elements.
23 Απρ 2020 · Solid hydrogen has a massive quantum zero-point energy (ZPE), far greater than its latent heat of melting, and has a Debye temperature well above melting. These factors determine the behavior of hydrogen in the dense state.
Due to its extremely low molecular mass, hydrogen gas is difficult to condense to a liquid (boiling point = 20.3 K), and solid hydrogen has one of the lowest melting points known (13.8 K). Figure \(\PageIndex{4}\): The Explosive Properties of Hydrogen.

1 Ιαν 2022 · The partition is dependent on the temperature. Normal hydrogen at room temperature is a mixture of 75% ortho and 25% para hydrogen. In the lower temperature range <80K, para hydrogen is the more stable form. At 20K, in thermal equilibrium, the concentrations are 99.8% para and 0.2% ortho.
