Why the gas constant 'R' is called universal gas constant?

One mole of a gas expands such that its volume 'v' changes with absolute temperature 'T' in accordance with the ralation V = HT^(2) where 'K' is a constant . If the temperature of the gas changes by 60^(@) C , then work done by the gas is (R is universal gas constant ) .

For a gas the value of (R)/(C_(v)) = 0 . 4 so the gas is (R-universal gas constant)

Two moles of helium gas (gamma=(5)/(3)) at 27^(@)C is expanded at constant pressure until its volume is doubled. Then it undergoes an adiabatic change until the temperature returns to its initial value. The work done during adiabatic process is ________ (universal gas constant = 8.3 "J mol"^(-1)K^(-1) )
