Question

How does the internal energy of the ice and water mixture change if the temperature does not rise while the ice is melting? No enough information to determine. It remains the same, because both are at the same temperature. It increases, because it takes more energy for water molecules to be disordered than to be ordered. It decreases, because you need to use energy to make a freezer run, but ice melts spontaneously. Suppose you start with 200 g of ice at 0 degree C. Calculate the amount of heat energy that must be transferred to the ice to melt it. (Use 334 kJ/kg for the latent heat of fusion. 2.26 times 103 kJ/kg for the l3tentheat of vaporization, and 4.19 kJ/kg degree C for the specific heat of water.) 450 kJ 45000 kJ 0.84 kJ 66.8 J 66.8 kJ 450 J Not enough information: you need to know how much water is with the ice. 838 kJ 6680 kJ
