The gas constant

universal phys. the constant R, entering the equation of state of 1 moles of the perfect gas: pv = RT (see Clapeyron equation), where r - pressure, v - volume, T - abs. rate -.pa. G. p. makes phys. sense of the work of expansion of 1 moles of perfect gas under the constant pressure with the heating on 10. From other side, a difference in the molar heat capacities at constant pressure and constant volume withr - cv = R (for all strongly rarefied gases). G. p. usually numerically is expressed in the following units:

J/deg- mole. . 8, 3143+-0, 00y2(y9'yagod) erg/deg- mole. . 8,eyya*y07 cal/deg-mole. . 1,986 l -atm/grad-mol7 of 82,0shch*y0-3

Universal g. p., in reference not to 1 mole, but to 1 molecule, NAZ. Boltzmann of constant.
