Solution

Dear User,
Ideal gas equation is PV = nRTUniversal gas constant, R = PVnT = Pressure×VolumeNumber of moles×Temperature = ForceArea×(Length)3Number of moles×Temperature(K) = Force(Length)2×(Length)3Number of moles×Temperature(K) = Force×LengthNumber of moles×Temperature(K) =Work doneNumber of moles×Temperature(K) = WorkK-1mol-1Thus, the universal gas constant R signifies the work done per Kelvin per mole or we can say that R signifies the work done when the temperature of one mole(n=1) of an ideal gas has been increased by 1K.
