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= ?

First, launch the video below. you will be asked to use your knowledge of physics to predict the outcome of an experiment. then, close the video window and answer the question at right. you can watch the video again at any point. part a as in the video, we apply a charge +q to the half-shell that carries the electroscope. this time, we also apply a charge –q to the other half-shell. when we bring the two halves together, we observe that the electroscope discharges, just as in the video. what does the electroscope needle do when you separate the two half-shells again? view available hint(s) as in the video, we apply a charge + to the half-shell that carries the electroscope. this time, we also apply a charge – to the other half-shell. when we bring the two halves together, we observe that the electroscope discharges, just as in the video. what does the electroscope needle do when you separate the two half-shells again? it deflects more than it did at the end of the video. it deflects the same amount as at end of the video. it does not deflect at all. it deflects less than it did at the end of the video. submit
