A 200-g metal container, insulated on the outside, holds 100 g of water in thermal equilibrium at 22.00C.
 
  A 21-g ice cube, at the melting point, is dropped into the water, and when thermal equilibrium is reached the temperature is 15.00C. Assume there is no heat exchange with the surroundings. For water, the specific heat is 4190 J/kg  K and the heat of fusion is 3.34  105 J/kg. The specific heat for the metal is closest to
  A) 3850 J/kg  K.
  B) 2730 J/kg  K.
  C) 4450 J/kg  K.
  D) 4950 J/kg  K.
  E) 5450 J/kg  K.

Question 2

A copper cylinder with a mass of 125 g and temperature of 345C is cooled by dropping it into a glass beaker containing 565 g of water initially at 20.0C.
 
  The mass of the beaker is 50.0 g and the specific heat of the glass is 840 J/kgK. What is the final equilibrium temperature of the system, assuming the cooling takes place very quickly, so that no energy is lost to the air? The specific heat of copper is 385 J/kgK and that of water is 4190 J/kgK.
