A block of ice at 0.000C is added to a well-insulated 147-g aluminum calorimeter cup that holds 200 g of water at 10.0C.
 
  The water and aluminum cup are in thermal equilibrium, and the specific heat of aluminum is 910 J/(kgK). If all but 2.00 g of ice melt, what was the original mass of the block of ice? The specific heat of water is 4190 J/(kgK), its latent heat of fusion is 334 kJ/kg, and its latent heat of vaporization is 2260 kJ/kg.
  A) 31.1 g
  B) 35.6 g
  C) 38.8 g
  D) 42.0 g
  E) 47.6 g

Question 2

A person makes ice tea by adding ice to 1.8 kg of hot tea, initially at 80C.
 
  How many kilograms of ice, initially at 0.00C, are required to bring the mixture to 10C? 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/(kgK).
  A) 1.0 kg
  B) 1.2 kg
  C) 1.4 kg
  D) 1.5 kg
  E) 1.7 kg
