A person makes iced tea by adding ice to 1.8 kg of hot tea, initially at 80C.
 
  How many kilograms of ice, initially at 0C, are required to bring the mixture to 10C? The specific heat of water (and tea) is 4186 J/kg  K, and the latent heat of fusion of ice is 3.34  105 J/kg. A) 1.0 kg
  B) 1.2 kg
  C) 1.4 kg
  D) 1.7 kg

Question 2

X-rays with a wavelength of 0.00100 nm are scattered by free electrons at 130 from their original direction.
 
  What is the kinetic energy (in keV) of each recoil electron? (melectron = 9.11  10-31 kg, c = 3.00  108 m/s, 1 eV = 1.60  10-19 J, h = 6.626  10-34 J  s)
