8) A person makes ice tea by adding ice to 1.8 kg of hot tea, initially at 80°C. How many kilograms of ice, initially at 0.00°C, are required to bring the tea to 0°C? The heat of fusion of ice is 334 k]/kg, and we can assume that tea has essentially the same thermal properties as water, so its specific heat is 4190 J/(kg.K).

Chapter 18, Problem 037 A person makes a quantity of iced tea by mixing 620 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 82°C, when thermal equilibrium is reached what are the mixture's temperature Tf and (b) the remaining mass mf of ice? If Ti 67°C, when thermal equilibrium is reached what are (c)...
