define universal gas and give value and si unit
lakshay1609:
R=8.314472 . it is define in term of energy per kelvin per mole
per kelvin
oo sorry
for wht sorry
but actually both can be there per kelvin and per mole

It is expressed in units of energy (that is, the pressure-volume product) per kelvin per mole. It is equivalent to the Boltzmann constant , except that the latter is expressed in units of energy per kelvin per particle. Denoted by the symbol R, the value of the gas constant is: R = 8.314472(15) J.

In terms of the pressure, volume, amount of substance, and temperature, the gas constant is equal to :R=(PV) /(NT) The gas constant has been found, by experiment, to have a value of approximately 8.3145 joules per kalvin per mole.
