Intuitively, one expects that each of these laws is a special case of a more general law. The Boltzmann constant is the ratio of the ideal gas constant to the Avogadro's constant. Values of the Universal Gas Constant "R" in various units. My teacher derived the gas law equation using classical mechanics: equations of motion, impulse, etc., that is, using pure theory alone. Chemical element with atomic number 7 Nitrogen, 7 N Nitrogen Appearance colorless gas, liquid or solid Standard atomic weight A r, std (N) [14.006 43, 14.007 28] conventional: 14.007 Nitrogen in the periodic table Hydrogen Helium Lithium Beryllium Boron Carbon Nitrogen Oxygen Fluorine Neon Sodium Magnesium Aluminium Silicon Phosphorus Sulfur Chlorine Argon Potassium Calcium Scandium … P V = n R T. The constant R is called the gas constant, and its physical significance will be explored in subsequent experiments. Boltzmann's Constant and Ideal Gas Constant. Recently in my physics class my imagination caught fire. V = constant AL n. In each of these laws, the identity of the gas is unimportant. where R is the universal gas constant, T the absolute temperature and RMM the relative molecular mass converson factor for the gas.
In SI units R = 8314.3 J/(kmol K) and T is in K. The conversion factor RMM has the numerical value of the relative molecular mass and the units kg/kmol in the SI system. That general law is called the Ideal Gas Law. the same regardless of the gas being considered. The atomic weight of elemental nitrogen, for example, in English units is A r,nitrogen = 14.0067 lbm/lbmol, and the molecular weight of air is ; Universal gas constant and ideal gas law. These tables contain 188 values for the Universal Gas Constant in the most likely combinations of units. Determining the General Gas Law Constant, R. OVERVIEW .

The universal gas constant (R u) is, as its name implies, universal, i.e. R is the gas constant in the ideal gas equation pV = nRT R is related to the Boltzmann constant, k, by R = k NA where k = 1.3806 x 10-23 J K-1, and N A = 6.022 x 10 23 mol-1 R with different units 8.31451 J K-1 mol-1 8.20578 x 10-2 L atm K-1 mol-1 8.31451 x 10-2 L bar K-1 mol-1 8.31451 Pa m3 K-1 mol-1 62.364 L Torr K-1 mol-1 1.98722 cal K-1 mol-1 The Gas Constant, R, in Various Units.
