A 295.0 g block of ice is cooled to -78^oC. It is added to 160 g of water in a calorimeter (of negligible specific heat) at a temperature of 25^oC. Please use the specific heats and latent heats from the equation sheet.

a. List neatly your knowns and unknowns.

b. Which gets to 0^oC first, the water or the ice? Make preliminary calculations to support your answer.

c. Does the one that gets to 0^oC first completely change phases? Make preliminary calculations to support your answer.

d. What is the final temperature of the system?

e. Determine the amount of ice that melts or the amount of water that freezes.
