Given that $1\mathrm{g}$ of water in liquid phase has volume $1{\mathrm{cm}}^3$ and in vapour phase $1671{\mathrm{cm}}^3$ at atmospheric pressure and the latent heat of vaporization of water is $2256\mathrm{J}/\mathrm{g}$; the change in the internal energy in joules for $1\mathrm{g}$ of water at $373\mathrm{K}$ when it changes from liquid phase to vapour phase at the same temperature is :
