The gas constant is denoted by the symbol R or R. It is equivalent to the Boltzmann constant, but expressed in units of energy per temperature increment per mole, i.e.

Helium gas constant

the pressure–volume product, rather than energy per temperature increment per particle. The constant is also a combination of the constants from Boyle's law, Charles's law, Avogadro's law, and Gay-Lussac's law. It is a physical … Allmänna gaskonstanten Allmänna gaskonstanten, R, är en konstant som uppträder i allmänna gaslagen och andra tillståndsekvationer för gaser. Den är en produkt av Boltzmanns konstant och Avogadros tal och har det numeriska värdet 8,3144621 (75) J mol -1 K -1. Helium carrier gas When using a constant pressure mode for carrier gas and temperature programming, the viscosity of the gas will increase and the average linear velocity will decrease.

The boiling and freezing points of helium are lower than those of any other known substance. Se hela listan på engineeringtoolbox.com Helium is the least water-soluble monatomic gas, and one of the least water-soluble of any gas (CF 4, SF 6, and C 4 F 8 have lower mole fraction solubilities: 0.3802, 0.4394, and 0.2372 x 2 /10 −5, respectively, versus helium's 0.70797 x 2 /10 −5), and helium's index of refraction is closer to unity than that of any other gas. The universal gas constant is R = 0,082057338(47) L.atm/mol.K.The specific gas constant is the ratio universal gas constant/molar mass. Divide the molecular weight of Helium (4.003 g/mol) into R, the universal gas constant, which is equal to 8.31447 Pa m^3/K/mol.

Explanation: The following assumptions have been made here: At specified conditions, helium can be treated as an ideal gas. Helium has constant specific heats at room temperature. 2006-07-12 for an ideal gas: p • v = K • T (3-1) 2 p, pressure, N/m Q T, specific molal volume, m /kg-mole R, universal gas constant, 8314.5 J/kg-mole • K T, absolute temperature, K. For a noble gas such as helium the real p-v-T relation deviates little from the real gas law at the pressure and the temperature in a reactor core. Helium, chemical element, inert gas of Group 18 (noble gases) of the periodic table.
