Value of universal gas constant (R)


 Value of universal gas constant (R) is the same for all gases. What is its physical significance?


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 8.3144598 joules per Kelvin per mole.

Hence R only depends on the unit of different parameter P, V, n, T. So R values the same for all gases.
