\mathrm{~kg}\) of water is vaporized in a container at the constant temperature of \(373 \mathrm{~K}\) and the constant pressure of \(1,01,325.0 \mathrm{~N} / \mathrm{m}^{2}\). The specific volume of liquid and vapour at these conditions are \(1.04 \times 10^{-3}\) and \(1.673 \mathrm{~m}^{3} / \mathrm{kg}\) respectively The amount of heat added to the water is \(2257 \mathrm{~kJ}\). Calculate the change in internal energy \((\Delta U)\) and enthalpy \((\Delta H)\).
