I take 2.0 kg of ice and dump it into 2.3 kg of water and, when equilibrium is reached, I have 4.3 kg of ice at 0°C. The water was originally at 0°C. The specific heat of water = 1.00 kcal/kg/°C, the specific heat of ice = 0.500 kcal/kg/°C, and the latent heat of fusion of water is 80.0 kcal/kg. The original temperature of the ice was
a. one or two degrees below 0°C.
b. –46.0°C.
c. –184°C.
d. 184°C.
e. The whole experiment is impossible.
