A 44.0-g block of ice at -15.0C is dropped into a calorimeter (of negligible heat capacity) containing 100g of water at 5.0C.
 
  When equilibrium is reached, how much of the ice will have melted? The specific heat of ice is 2090 J/kg  K, that of water is 4186 J/kg  K, and the latent heat of fusion of water is 33.5  104 J/kg. A) 2.1 g
  B) 21 g
  C) 5.2 g
  D) 52 g
  E) 4.4 g

Question 2

A 29.0-pm-wavelength photon is scattered by a stationary electron.
 
  What is the maximum energy loss the photon can have? (melectron = 9.11  10-31 kg, c = 3.00  108 m/s, h = 6.626  10-34 J  s, 1 eV = 1.60  10-19 J)
  A) 15 keV B) 4.0 keV C) 6.1 keV D) 10 keV E) 12 keV
