During a 10 minute period, 30 grams of steam condenses into water. How much energy flowed out of the water-steam mixture? (Signs Matter!)Assuming that all of the energy flowing out of the water-steam mixture goes into the water-ice mixture, how many grams of ice melts? What is the change in the entropy of the water-steam mixture at 100C? (Signs Matter!)What is the change in the entropy of the water-ice mixture at 0C? (Signs Matter!) (Verify to yourself that the 2nd law of thermodynamics is satisfied)
