Specific gas constant he
WebMay 7, 2024 · The specific heat constants for constant pressure and constant volume processes are related to the gas constant for a given gas. This rather remarkable result has been derived from thermodynamic relations, which are based on observations of physical systems and processes. WebFor one mole, therefore, PV / T = R. The dimensions of the universal gas constant R are energy per degree per mole. In the metre-kilogram-second system, the value of R is 8.31446261815324 joules per kelvin (K) per mole. The universal gas constant is defined as Avogadro’s number NA times the Boltzmann constant k. Britannica Quiz.
