Homework Help: Heat problem

  1. Jun 7, 2005 #1
    I have a question and I think it has too many unknowns, but here it is:

    Two spheres, labeled A and B, have identical masses, but are made of different substances. The specific heat capacity of sphere A is 440 J/kg*C . The spheres are initially at 21 degrees C; and the same quantity of heat is added to each sphere. If the final temperature of sphere A is 72 degrees C, what is the final temperature of sphere B?

    Help please.
