A 360-g metal container, insulated on the outside, holds 180.0 g of water in thermal equilibrium at 22.0C.
 
  A 24.0-g ice cube, at the melting point, is dropped into the water, and when thermal equilibrium is reached the temperature is 15.0C. Assume there is no heat exchange with the surroundings. For water, the specific heat capacity is 4190 J/kg  K and the heat of fusion is 3.34  105 J/kg. What is the specific heat capacity of the metal of the container?
  A) 970 J/kg  K
  B) 2800 J/kg  K
  C) 1700 J/kg  K
  D) 2300 J/kg  K
  E) 3300 J/kg  K

Question 2

A diatomic molecule is vibrating in the v = 1 quantum state with a frequency of 2.0  1013 Hz.
 
  What is its vibrational energy? (1 eV = 1.60  10-19 J, h = 6.626  10-34 J  s)
  A) 0.12 eV B) 0.17 eV C) 0.041 eV D) 0.083 eV
