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).
4 Νοε 2012 · Online calculator, figures and tables showing density and specific weight of hydrogen, H2, at temperatures ranging from -260 to 325 °C (-435 to 620 °F) at atmospheric and higher pressure - Imperial and SI Units.
Questions of lattice packing and how to achieve even mixing of solids are important. The important engineering properties of solid hydrogen fall into the following categories: Mechanical, Thermal, Thermodynamic, Chemical, Optical, and Others. Reference Data on Solid Hydrogen.
6 Οκτ 2020 · a Equation of state (EOS) for liquid and solid H 2 at selected temperatures. The green and blue solid line is the EOS of Phase I at 300 K and T m (melting point), respectively.
21 Ιουλ 2016 · The solid hydrogens are dominated by quantum effects, the most out standing property being that the rotation of the molecules is free down to the lowest temperatures, in the sense that the rotational quantum number J characterizing the rotational motion of the free molecules remains a good quantum number in all of the solid-state phases ...
22 Αυγ 2022 · At low enough temperatures, all substances are solids (helium is the lone exception), but the temperature at which the solid state becomes the stable phase varies widely among substances, from 20 K (−253°C) for hydrogen to over 3,900 K (3,600°C) for carbon.
In this paper thermal data on hydrogen in its various isotopic and ortho-para modifications are compiled and correlated. Data on properties of the gaseous, liquid, and solid states are presented in tables and graphs, and by use of formulas. Thermodynamic properties are given for the ideal gas state. In addition, tables based on the PVT
