Calculate the increase in the internal energy of

Question:

Calculate the increase in the internal energy of $10 \mathrm{~g}$ of water when it is heated from $0^{\circ} \mathrm{C}$ to $100^{\circ} \mathrm{C}$ and converted into steam at $100 \mathrm{kPa}$. The density of steam $=0.6 \mathrm{~kg} / \mathrm{m}^{3}$. Specific heat capacity of water $=4200 \mathrm{~J} / \mathrm{kg}^{-}{ }^{\circ} \mathrm{C}$ and the latent heat of vaporization of water $=2.5 \times 10^{6} \mathrm{~J} / \mathrm{kg}$.
