$\displaystyle 1$ g of water, of volume $\displaystyle 1 \mathrm{~cm}^3$ at $\displaystyle 100^{\circ} \mathrm{C}$, is converted into steam at same temperature under normal atmospheric pressure $\displaystyle \simeq 1 \times 10^5 \mathrm{~Pa}$. The volume of steam formed equals $\displaystyle 1671 \mathrm{~cm}^3$. If the specific latent heat of vaporization of water is $\displaystyle 2256$ J/g, the change in internal energy is :
Official answer
(2)
$\displaystyle 2089$ J
