Helium phase diagram. Online Helium Density Calculator. The calculator below can be used to estimate the density and specific weight of helium at given temperature and pressure. The output density is given as kg/m 3, lb/ft 3, lb/gal(US liq) and sl/ft 3. Specific weight is given as N/m 3 and lb f / ft 3.
Solid helium has a density of 0.214 ± 0.006 g/cm 3 at 1.15 K and 66 atm; the projected density at 0 K and 25 bar (2.5 MPa) is 0.187 ± 0.009 g/cm 3. At higher temperatures, helium will solidify with sufficient pressure. At room temperature, this requires about 114,000 atm.
Find the density of helium at atmospheric pressure and other physical and thermal properties of helium at 25 o C and 1 atm. See also the links to get values for helium at varying pressure and temperature.
Density (g cm −3) Density is the mass of a substance that would fill 1 cm 3 at room temperature. Relative atomic mass The mass of an atom relative to that of carbon-12. This is approximately the sum of the number of protons and neutrons in the nucleus. Where more than one isotope exists, the value given is the abundance weighted average. Isotopes
Find the density of helium in different units, such as kg/m3, g/mL, oz/cu in, lb/cu ft, and more. Use the calculator to convert mass and volume of helium.
21 de nov. de 2020 · Learn about the density of helium and other elements, how it depends on atomic mass, number, pressure and temperature, and how to calculate it. Find the densest and lightest materials on earth and compare them with Hassium and neutron stars.
A report on the thermophysical properties of helium at pressures from 1 to 100 bar and temperatures from 273 to 1800 K. The report presents equations for density, specific heats, viscosity, thermal conductivity, and Prandtl number based on a literature survey and intermolecular potential functions.
