question 11

Multiple Choice

Calorimetry: 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 mixture to 10°C? The heat of fusion of ice is 334 kJ/kg, and we can assume that tea has essentially the same thermal properties as water, so its specific heat is 4190 J/(kg ∙ K) .

• A) 1.0 kg
• B) 1.2 kg
• C) 1.4 kg
• D) 1.5 kg
• E) 1.7 kg
