Exercise problem

Calculate $U$ and $H$ for $1kg$ of water when it is vaporized at the constant temperature of $100C$ and the constant pressure of $101\mathrm{.}33$kPa. The specific volumes of liquid and vapor water at these conditions are $0\mathrm{.}00104$ and $1\mathrm{.}673m^{3}k{g}^{-1}.$For this change, heat in the amount of $2,256\mathrm{.}9kJ$ is added to the water. It is assumed that the vaporization process is reversible.
