How much thermal energy must be removed from 456 g of water at 25.0C to change it into ice at -10.0C?
 
  The specific heat of ice is 2090 J/kg  K, the latent heat of fusion of water is 33.5  104 J/kg, and the specific heat of water is 4186 J/kg  K.
  A) 105 kJ
  B) 153 kJ
  C) 57.3 kJ
  D) 47.7 kJ
  E) 210 kJ

Question 2

A plastic cube is immersed in water having an index of refraction of 1.33. A laser beam in the plastic strikes the interface at an angle of 14.5 with the normal in the plastic. In the water, this beam makes an angle of 21.8 with the normal.
 
  What is the speed of light in the plastic cube? (c = 3.0  108 m/s)
