Two metal objects, A and B, each of mass 60.0 g, are prepared at different temperatures. They are brought into thermal contact and allowed to reach thermal equilibrium while insulated from the rest of the universe (i.e. no heat exchange). Object A has a specific heat of C = 0.160 J/g-K, and object B has a specific heat of cs = 0.200 J/g.K. (a) If the final temperature (in K) of the system is 320 K (thermal equilibrium), and the initial temperature of object B is 256 K, what is the initial temperature of object A? 400 QUESTION 14 Continuation of the previous problem (b) What is the entropy change (in J/K) for the system of two objects as they go through the process of reaching thermal equilibrium?
