Assuming that water vapour in an ideal gas, the internal energy change

1.	Assuming that water vapour in an ideal gas, the internal energy change (DeltaU) when 1 mol of water is vaporised at 1 bar of pressure and 100^(@) C, (Given : Molar enthalpy of vapourization of water at 1 bar and 373 K = 41 kJ mol^(-1) and R=8.3 J mol^(-1)K^(-1)) will be :
