Full Answer
R is most commonly used in the equation PV = nRT, which is the ideal gas law. The variable P is the pressure, V is the volume, n is the number of moles and T is the temperature. The universal gas constant is also used in the equation R = work/(amount x temperature). The exact value of R is based on the speed of sound in the gas argon.
