Suppose 0.6 kg of ice at 0°C is placed in 9.8 kg of water at 23.5°C. Calculate the final equilibrium temperature in Celsius. Lf = 3.35 x 105 J/kg; c = 4190 J/(kg⋅K). [Hint: There are two possible outcomes - the ice will be either fully or partially melted. Start by figuring out which occurs in this case.]
