A 3.2-kg block of iron (c=0.11 kcal/kgoC) that has been brought to a temperature of 1,045oC is placed on top of a 2.4-kg block of ice (c=0.5 kcal/kgoC) that has been cooled to -50oC. Assuming no heat is lost to the surrounding container, what is the final temperature of the iron block? (Your answer should be given to the nearest oC.)
