A person makes a quantity of iced tea by mixing 690 g of hot tea (essentially water) with an equal mass of ice at its melting point. Assume the mixture has negligible energy exchanges with its environment. (a) If the tea's initial temperature is T; = 96°C, when thermal equilibrium is reached what are the mixture's temperature Tand (b) the remaining mass m; of ice? If T; = 68°C, when thermal equilibrium is reached what are (c) T; and (d) m? The specific heat of water is 4186 J/kg-K. The latent heat of fusion is 333 kJ/kg.
