Itake 1.0 kg of ice and dump it into 1.0 kg of water and, when equilibrium is reached, i have 2.0 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 = 0.50 kcal/kg⋅°c, and the latent heat of fusion of water is 80 kcal/kg.
the original temperature of the ice was:
a. one or two degrees below 0°c. b. −80°c. c. −160°c. d. the whole experiment is impossible.

Tafari worked one summer on a ship that set weather buoys in the ocean. he watched how one of the buoys moved in the water. describe which parts of the wave would cause the buoy to bob up and down. which wave property determined how fast the buoys bobbed in the water? he observed that when the wind blew harder, the ocean waves were larger, and the buoys moved away from the ship. what effect, if any, did the waves have on how far the buoys moved? explain your answer.

Carbon is allowed to diffuse through a steel plate 15 mm thick. the concentrations of carbon at the two faces are 0.65 and 0.30 kg c/m^3 fe, which are maintained constant. if the preexponential and activation energy are 6.2 x 10-7 m2 /s and 80,000 j/mol, respectively, compute the temperature at which the diffusion flux is 1.43 x 10^-9 kg/m^2 -s.
