A person pours 330 g of water at 45C into an 855-g aluminum container with an initial temperature of 10C. The specific heat of aluminum is 900 J/(kgK) and that of water is 4190 J/(kgK).
 
  What is the final temperature of the system, assuming no heat is exchanged with the surroundings? A) 28C
  B) 32C
  C) 31C
  D) 33C
  E) 35C

Question 2

If you add 700 kJ of heat to 700 g of water at 70.0C, how much water is left in the container? The latent heat of vaporization of water is 2.26  106 J/kg and its specific heat is is 4190 J/(kgK).
 
  A) 429 g
  B) 258 g
  C) 340 g
  D) 600 g
  E) none
