Problem- An 66.39 g sample of aluminum is placed on a 42.56 g sample of copper initially at 124.96oC. If the heat is only transferred between the metals (with no loss to the surroundings) and the final temperature of both metals is 44.29oC, what is the initial temperature (in oC) of aluminum?
Anyone can tell me how to solve it step by step so that I will be able to understand what is going on?
