10 kg of liquid water is in a container maintained at atmospheric pressure, 101325 Pa. The water is initially at 373.15 K, the boiling point at that pressure. The latent heat of water -> water vapor is 2230 J/g. The molecular weight of water is 18 g. 103 J of heat is added to the water.1) How much of the water turns to vapor? Answer = mass(vapor)= .4482) By how much did the Gibbs free energy change? Gfinal-Ginitial= ?3) By how much did the entropy change? Sfinal-Sinitial= ?4) By how much did the total (liquid +vapor) enthalpy H=U+pV change? Hfinal-Hinitial= ?5) By how much did the volume change, treating the vapor as an ideal gas and the liquid as having negligible volume? Vfinal-Vinitial= ?6) By how much did the total energy (liquid +vapor) change? Ufinal-Uinitial= ?
