A 2 L bottle of a carbonated beverage (Coke) at 20 °C is placed in a cooler with 10 L of saturated liquid water and 30 kg of ice (both at 0.01 °C). Assuming no heat transfer with the surroundings, (a) determine how much ice has melted to bring the temperature of the beverage to equilibrium with the ice/water. (b) Determine the final equilibrium temperature
