1) A 565g cube of iron is cooled form the temperature of boiling water to room temperature (20C).

a. How much heat must be absorbed by the cube?

b. If the iron is cooled by dunking it into water at 0C, how much water is needed?

2) A .50kg sample of water is at 15.0C in a calorimeter. A 0.040 block of zinc at 115C is placed in the water. Find the final temperature of the system.
