Water is heated at a constant pressure of \(0.7 \mathrm{mPa}\). The boiling point is \(164.97^{\circ} \mathrm{C}\). The initial temperature of the water is \(0^{\circ} \mathrm{C}\). The latent heat of evaporation is \(2066.3 \mathrm{~kJ} / \mathrm{kg}\). Find the increase in entropy of water, if the final state is steam.
