250 mL of soda at 27C is added to a glass with 10g of ice at 0 C. 1. How much heat is required to melt the ice? 2. Assuming all the heat required to melt the ice flowed from the soda, is the temperature of the soda after the ice melts? assume the specific heat of soda is the same as that of water. 3. Room temperature is 23C. What is the total change in entropy of the glass of cold soda after it comes to thermal equilibrium with the room?
