Chapter 8 Problem 8.87

For this problem, the solution book uses three different specific heat capacities for water, but I thought we could just always use 4.18 J/ C x g?

That is ONLY for calculations with liquid water. If you are using other phases, use that phases' heat capacity. For example the specific heat of ice is ~ 2.03 and the specific heat of vapor is different as well. These will be given on the midterm on the constants and equations sheet.
