In an experiment to measure the thermal conductivity of a certain material, a slab of material 10.0 mm thick separates a steam chamber from a block of ice with a square cross-section with dimensions 8.00 cm  8.00 cm.
 
  After 5.00 min of running the experiment, 64.0 g of ice have melted. What is the thermal conductivity of this material? The latent heat of fusion of water is 33.5  104 J/kg, the latent heat of vaporization of water is 2.256  106 J/kg, and both the ice and water are under 1.00 atm of pressure.
  A) 0.130 W/m  K
  B) 0.250 W/m  K
  C) 0.440 W/m  K
  D) 0.620 W/m  K
  E) 1.12 W/m  K

Question 2

A diatomic has a moment of inertia of 7.73  10-45 kg m2. What is its rotational energy in the quantum state characterized by l = 2? (h = 6.626  10-34 J  s, h = 1.055  10-34 J  s, 1 eV = 1.60  10-19 J)
 
  A) 87.1 eV B) 27.0 eV C) 72.2 eV D) 587 eV E) 22.7 eV
