Value of universal gas constant (R) is same for all gases. What is its physical significance?
Unit of R depends upon these units in which p, V and T are measured as, . If pressure is measured in Pascal, per mole volume is measured in m3 and temperature is measured in Kelvin then units of 'R' are or . Since, joule is the unit of work done, so 'R' is work done by the gas per mole per Kelvin.
