QUESTION 8 How does the internal energy of the ice and water mixture change if the temperature does not rise while the ice is melting? It decreases, because you need to use energy to make a freezer run, but ice melts spontaneously. No enough information to determine. It increases, because it takes more energy for water molecules to be disordered than to be ordered. It remains the same, because both are at the same temperature. QUESTION 9 Suppose you start...
