Consider two identical iron nails: One nail is heated to 95 °C, the other is cooled to 15 °C. The two nails are placed in a coffee cup calorimeter and the system is allowed to come to thermal equilibrium. What is the final temperature of the two nails?

Is water in the calorimeter"? If not, then
mass Fe x sp.h.Fe x (Tf-95) + mass Fe x sp.h.Fe x (Tf-15) = 0
Tf = 55 if I did it right. Check my work. Since mass and sp.h. are the same, the easy way is to assign arbitrary numbers to mass and sp.h. (I used 1 to make it easier).
