Recitation 11 Problem 2 Eight fluid ounces (1 qt = fl 32 oz) of a beverage in a glass at 23.0 °C is to be cooled by adding ice and stirring. The properties of the beverage may be taken to be those of liquid water. The enthalpy of the ice relative to liquid water at the triple point is -348 kJ/kg. Estimate the mass of ice (g) that must melt to bring the liquid temperature to 4.0 °C, neglecting energy losses to the surroundings. (Note: For this isobaric batch process, the energy balance reduces to Q = AH)
